I was confused, by my git SVN import of the OSG source tree, about
what commits are in 2.8.3. I'll check in a correction soon.

  2.9.10.
  I will not conditionalize code in fgfs based on individual revisions of OSG
  SVN; if you are using OSG SVN, then you are, by definition, living on the
  bleeding edge.

 Hi Tim,

 Your commit broke SimGear for me (using OSG 2.8.1). I have attached a
 tiny patch that restores the ability to compile the last SG git
 revision with OSG 2.8.1
 Could you please review it and apply it if it makes sense ?

 Your patch doesn't work for OSG = 2.9 because _readerWriterOptions is
 unconditionally used in SGPagedLOD.cxx

 By the way, I committed the changes to releases/2.2.0 and then merged that 
 branch into next. This is the way fixes should move between the two branches. 
 Please don't commit a fix to next and then cherry-pick it to the release 
 branch. It is very messy to have the same change committed on several 
 different branches. 

I tried that on the data repo without luck. Many Aircraft are removed for the 
release, and merging propagate that in master.

 I find it ridiculous and a bit immature how Oliver people whine about
 a simple logo.

It is neither ridiculous nor immature.

Unfortunately the reality of the world that we live in is that
Intellectual Property licensing is very important, particularly for a
project such as FlightGear where we are all volunteers

While you may not see it as an issue, and be prepared to fight in
court, by having someone include the logo in the git repository we
would be making them, and possibly all the git maintainers, personally
liable for any infringement.

Red Bull might not care, but if they did, the costs of defending such
legal challenges would be huge, even if we were not infringing. If you
have no assets you might not be a target, but I have sufficient assets
and a wife and child to think about - it is simply not worth the risk.

Approaching Red Bull directly (as noted in the topic) seems by far the
most sensible option here. I would be very interested in what they
say, but I strongly suspect at the very least it would have some
non-commercial clause that would be incompatible with the GPL.

 If Oliver really cared about preventing fictitious lawsuits as he
 claims to, he would concentrate his efforts on the several red bull
 logos that are already in our database.

IMO these need to be removed. Could you list them please so we can get
in touch with the maintainers?

FYI, when I initially created the Pitts biplane for FG, it had a Duff
Beer livery, after the beer in The Simpsons. So, a wholly fictious
brand in a cartoon. After some discussion, we decided that this wasn't
really appropriate and it was removed from (then) cvs. So, you're not
the first to be in this position.

 If this thread is further interfered with, I will be forced to result
 to more forceful methods of having my work committed, or I may very
 well change the license back to the CC license and our community will
 have missed out on a very high quality aircraft.

I don't think posting to the FlightGear-Dev list can be considered
interfering. It is after all, a discussion group :)

It is important that these issues are discussed - and this is exactly
the correct forum for this.

I think you will find that any other git committer will want to
discuss these issues in an open forum and come to a consensus view
rather than just committing such work. I expect that they would have
exactly the same concerns as me.

This is not an issue with GPL/CC licensing. You are perfectly entitled
to release your aircraft with the Red Bull livery under the GPL - in
fact you have already done so! The issue is whether it is something
that we can risk adding to the core FG repository.

Note that to change to a CC license, you would need to get permission
from all the contributors to the aircraft. From reading the Forum
topic, it would appear to be a great example of cooperation between
many different people.

Frankly such threats of changing the license are beneath you.

Yes, for fgdata merging back from the 2.2.0 branch will not work.

I'm a bit at loss why the 2.2.0 branch was reduced to contain only the 
data package contents instead of being a snapshot of everything to 
be included in the release - presumably there will be archives for the 
download page generated also for the aircraft removed in the 2.2.0 
branch. Hopefully their state in master will still be 2.2.0 compatible at 
that time..

For the next release maybe we could create two release branches in data
2.x.0-full and 2.x.0-datapackage, where the first serves as the full 
data release and the latter whatever purpose (snapshot generation?) the 
2.2.0 branch serves now.

Sorry, but I have worked in this area and they are out to kill as interest

Flightgear  needs to avoid them completely, unless - we have permission

To have permission we need someone/something/entity to have agreement with..

Indeed PJ is very handy, my dream would be she could represent FG, lots of

Jack,

You know who takes trademark law seriously?  Trademark owners.

An owner must protect their trademarks from being used in ways that 
decrease the value to them.  This tends to be two areas, one very 
specific and the other kind of broad.  The first thing they must protect 
against is their trademark becoming generic; if everyone refers to an 
adhesive bandage as a Band-Aid, then Johnson and Johnson, who owns 
that trademark, runs the risk of losing the exclusive use of it.  In 
fact, they made their advertising jingle many years ago to include 
stuck on Band-Aid brand as a very public way of asserting their 
ownership of the brand.  Did you know Otis Elevator company came up with 
and trademarked the name escalator?  They did not actively (enough) 
assert their ownership of that trademark and have lost any rights of 
exclusivity to it.  It is now a generic term that any company can use to 
refer to stairs that move or anything else, for that matter.  In these 
cases, it is an *urgent* obligation of the trademark owner to sue the 
pants off of any infringer.

The remaining broad category is your trademark being used in any other 
way that decreases its value to you.  This can be using it to refer to 
products or things it isn't intended to be associated with, removing the 
focus from the owner's product(s).  Worse are cases where a trademark is 
used in ways that are harmful to the image of the owner or the owner's 
products.

A hopefully imaginary example here might be the questionable marketing 
practices of certain people who are selling FlightGear to the public.  
Hell, even *we* don't want to be associated with them... why would Red 
Bull (tm) like it any better?   They have much more to lose, in terms of 
gross dollars, than anyone here does if their trademarks were to become 
associated with misbehavior.  So, you might say, let them go after 
ProSimFraud if they are misbehaving.  The ProFraudSimulator people would 
simply point to FlightGear and say, hey this is Open Source and *they* 
did it!

This topic has come up here before and I even checked with American 
Airlines about use of their logos/trademarks.  Their answer was dense 
legal talk that I roughly translated to mean we realize we can't stop 
everybody from using our logos, but boy howdy, we have the right to kick 
your ass in court if you do it and tick us off!

How is open source Red Hat Enterprise different from open source 
CentOS?  Trademarks.  The words Red Hat and any logos owned by them 
are completely removed by the CentOS group, leaving the only 
encumbrances those obligations covered by the GPL.  It's kind of neat 
that you can take a Red Hat installation, point it to a CentOS 
repository instead of the Red Hat network and have it install updates.  
When the updates are complete, Ta dah!  You now have a CentOS branded 
installation.  Back on point, Red Hat differentiates its products by the 
services they provide and the *trademarks* that they own.  Sure, you can 
use their operating system code freely, but not their services or 
*trademarks*.  Like American Airlines, they have the right to kick your 
ass in court for doing so.

If the Red Bull were to get litigious on us, they'd have to put some 
names on the law suit.  There isn't a FlightGear Foundation or any 
single entity responsible for FG, so right at the top of the list would 
be names near and dear to us, starting with Curtis Olson.  The list of 
defendants would probably include anyone else identified as being 
responsible for the infringement, such as whoever committed the livery 
to git and whoever participated in releasing the

Red Bull is known to be very restrictive sensitive when it comes to
commercial use of their trademarked material.  Therefore I'd call it
unjustifiable to put the FlightGear project at risk of facing a legal
battle.

2011-02-16 Thread Curtis Olson
I hate to wade into mud wrestling matches.  But for every one who is on
their high horse about being pristine in our non-use of any possible
trademarked items ... have you browsed through our aircraft?  We have
liveries from just about every airline imaginable, past and present.

What I don't like to hear is arguments along the line of: person A can't
submit anything that could ever possibly be a trademark infraction by
anyone's estimation, but person B we will let get away with it.  Oh and by
the way, we really should go through our repository and clean out any
possible trademark infringements ... maybe some day.

First of all this smacks of targeting or interpreting our policy differently
for different people... and that usually is done on the basis of some other
agenda.  Maybe the person in question has invited some of this, maybe they
haven't, but applying our policies in different measures to different people
can quickly get petty and immature.

Second, saying that oh I wish we'd retroactively fix our repository to
honor this policy perfectly, and then doing nothing about it also is really
weak.  It sounds good on the face of it, but at the end of the day what
matters is action, not words.

I think it's pretty accepted that flight simulators can reproduce company
liveries in the process of realistically modeling the world.  I know that
has been widely debated (AA, et. al) but the reality is that people are
creating liveries of all kinds of companies all the time.

Where do we draw the lines?  Is it ok to reproduce an airline livery, but
not some other company livery?  As far as I can tell the people arguing that
we can't have a red bull logo are on really shaky ground from a
consistency perspective.

Do you want to argue this from a legal standpoint?  Do we only include
anything that we have written permission from the original company to use?
 In that case probably we'll have to rip out half of our simulator.  How far
do we want to take it?  Do you think aircraft manufacturers have given us
explicit permission to replicate their designs?  Aircraft systems and
cockpit displays?  Tire manufacturers?  ACME rivet company?  I've got
nothing on file from them.  Building shapes and names and logos?  If we have
to get written permssion to replicate anything, then we might as well pack
it all up and go home, as should every other simulator developer.

I only wade in because this whole thing smacks of a pissing match and I get
strong indication that our policies are being selectively interpreted by
some to gain an advantage in this stupid pissing match and not for the
benefit and quality and safety of the FlightGear project itself.

Thank you,

Curt.

their trademark in return for free  advertising for them. I don't know how
several RC aircraft makers 'solved' this issue. There are several RC
aircraft with the Red Bull livery in addition to several other trademarked
liveries. However, one never really knows how lawyers will react on a case
by case basis.

 Hi,

 I find it ridiculous and a bit immature how Oliver people whine about 
 a simple logo.

 If Oliver really cared about preventing fictitious lawsuits as he 
 claims to, he would concentrate his efforts on the several red bull 
 logos that are already in our database.

Jack,

You know who takes trademark law seriously?  Trademark owners.

An owner must protect their trademarks from being used in ways that decrease
the value to them.  This tends to be two areas, one very specific and the
other kind of broad.  The first thing they must protect against is their
trademark becoming generic; if everyone refers to an adhesive bandage as a
Band-Aid, then Johnson and Johnson, who owns that trademark, runs the risk
of losing the exclusive use of it.  In fact, they made their advertising
jingle many years ago to include stuck on Band-Aid brand as a very public
way of asserting their ownership of the brand.  Did you know Otis Elevator
company came up with and trademarked the name escalator?  They did not
actively (enough) assert their ownership of that trademark and have lost any
rights of exclusivity to it.  It is now a generic term that any company can
use to refer to stairs that move or anything else, for that matter.  In
these cases, it is an *urgent* obligation of the trademark owner to sue the
pants off of any infringer.

The remaining broad category is your trademark being used in any other way
that decreases its value to you.  This can be using it to refer to products
or things it isn't intended to be associated with, removing the focus from
the owner's product(s).  Worse are cases where a trademark is used in ways
that are harmful to the image of the owner or the owner's products.

A hopefully imaginary example here might be the questionable marketing
practices of certain people who are selling FlightGear to the public.  
Hell, even *we* don't want to be associated with them... why would Red 
Bull (tm) like it any better?   They have much more to lose, in terms of 
gross dollars, than anyone here does if their trademarks were to become
associated with misbehavior.  So, you might say, let them go after
ProSimFraud if they are misbehaving.  The ProFraudSimulator people would
simply point to FlightGear and say, hey this is Open Source and *they* did
it!

This topic has come up here before and I even checked with American Airlines
about use of their logos/trademarks.  Their answer was dense legal talk that
I roughly translated to mean we realize we can't stop everybody from using
our logos, but boy howdy, we have the right to kick your ass in court if you
do it and tick us off!

How is open source Red Hat Enterprise different from open source CentOS?
Trademarks.  The words Red Hat and any logos owned by them are completely
removed by the CentOS group, leaving the only encumbrances those obligations
covered by the GPL.  It's kind of neat that you can take a Red Hat
installation, point it to a CentOS repository instead of the Red Hat network
and have it install updates.  
When the updates are complete, Ta dah!  You now have a CentOS branded
installation.  Back on point, Red Hat differentiates its products by the
services they

 This is ridiculous. We have this discussion every so often, when we are not

 copyright infringement. We ways end up with this solution.

 Simples.

I think we would be safer not having real life airliner liveries. I
recall that MSFS 2002 (or was it 2004?) used fictional liveries,
presumably to avoid this entire issue. I don't know what FS-X does.

In the case of airliner liveries there is a history of them being used
in flight simulators. IANAL, but AFAIK the fact that they have been
used for a number of years without any enforcement from the trademark
owner can be considered precedent in court that the owner is not that
fussed about the use and makes enforcement more difficult in the
future.

I just had a quick look on avsim.com to see if add-on aircraft are
being sold with real life liveries, and they are. I'd be interested to
find out what licensing they have, if any. Nevertheless, if I was a
commercial FS aircraft developer or commercial FG distributor, I'd be
quite nervous about including trademarked liveries.

As Martin points out Red Bull is very careful about their trademark
licensing  - I guess it's because they are very much a brand who
sponsors a whole load of liveried products, teams etc. on the back of
a rather sweet caffeinated drink (IMO it's a bit like Buckfast without
the alcohol ;) )

As I said above, I think asking for permission is the right approach
here, and I'd be interested in the response.

Hi Curt,

At the risk of being a case of if the hat fits

Yes, and as I said in the other post (which crossed in the ether with
yours), I personally think that's a mistake and a legal risk (albeit a
small one).

 What I don't like to hear is arguments along the line of: person A can't
 submit anything that could ever possibly be a trademark infraction by
 anyone's estimation, but person B we will let get away with it.  Oh and by
 the way, we really should go through our repository and clean out any
 possible trademark infringements ... maybe some day.
 First of all this smacks of targeting or interpreting our policy differently
 for different people... and that usually is done on the basis of some other
 agenda.  Maybe the person in question has invited some of this, maybe they
 haven't, but applying our policies in different measures to different people
 can quickly get petty and immature.

I don't think I am holding Jack's work to a higher standard than anyone else
here, though other committers may have different standards to me.

As mentioned on the other post, I'm applying the same standards I've applied
to my own work based on discussions on this list:

http://www.mail-archive.com/flightgear-devel@lists.sourceforge.net/msg13303.html

(Oh, that brings back memories - we were all so young, a new aircraft
was a big deal, CVS)

Melchior's comment is an interesting one, but I've no idea if it has
any legal basis.

 Second, saying that oh I wish we'd retroactively fix our repository to
 honor this policy perfectly, and then doing nothing about it also is really
 weak.  It sounds good on the face of it, but at the end of the day what
 matters is action, not words.

It might also lead to a commit war, which would be bad. I'd much prefer a clear
policy at a project level and then consistency with that policy.

At present I don't think we have a policy - though it's possible that
my experience
with the Pitts is an exception and we are quite happy to use trademarks in the
data package.

It sounds like your view is that including trademarks in the data repository is
perfectly OK. Correct?

If that's the case and the majority of devs agree then I'll bite my tongue,
though like Melchior I won't commit it myself.

 I think it's pretty accepted that flight simulators can reproduce company
 liveries in the process of realistically modeling the world.  I know that
 has been widely debated (AA, et. al) but the reality is that people are
 creating liveries of all kinds of companies all the time.
 Where do we draw the lines?  Is it ok to reproduce an airline livery, but
 not some other company livery?  As far as I can tell the people arguing that
 we can't have a red bull logo are on really shaky ground from a
 consistency perspective.

See my post which crossed with yours. I think where there is precedent we're
(relatively) OK. the danger lies in trademarks that have not been used regularly
within simulators and which have litigious owners.

 Do you want to argue this from a legal standpoint?  Do we only include
 anything that we have written permission from the original company to use?
  In that case probably we'll have to rip out half of our simulator.  How far
 do we want to take it?  Do you think aircraft manufacturers have given us
 explicit permission to replicate their designs?  Aircraft systems and
 cockpit displays?  Tire manufacturers?  ACME rivet company?  I've got
 nothing on file from them.  Building shapes and names and logos?  If we have
 to get written permssion to replicate anything, then we might as well pack
 it all up and go home, as should every other simulator developer.

There is a legal difference between objects/copyright and trademarks which is
important. We could fairly easily have aircraft liveries and buildings that do
not infringe trademarks.

 I only wade in because this whole thing smacks of a pissing match and I get
 strong indication that our policies are being selectively interpreted by
 some to gain an advantage in this stupid pissing match and not for the
 benefit and quality and safety of the FlightGear project itself.

I don't think there's much of a pissing match going on here - I encouraged Jack
to release his AH-1 under the GPL and committed the original version to git, so
to suggest I have an axe to grind is mistaken.

I admit I'm being paranoid here, and that there is a gray area. However, I think
it is a good idea to air these issues on the list.

[Flightgear-devel] FlightGear model animation question

2011-02-16 Thread Curtis Olson
I was browsing the flightgear wiki pages on doing model animations.
 Everything is written from the perspective of a single model with named
parts and the animations refer to the part names.

What I have here is two version of the same model as separate 3ds files.  I
realize it's a crude hack, but I'm short on time.  What I would like to do
is create an animation that selects one entire model or the other depending
on the state of a property.  I assumed it would be easy to do so I left it
to the last minute ... I've probably done it in the past, but now I can't
find any documentation or examples ... is this possible to do?

Thanks,

Curt.

Curt,

One way to do this, set up the primary model XML file:

?xml version=1.0?
PropertyList

pathmymodel.ac/path

model
  nameModel1/name
  pathAircraft/myplane/Models/model_1.xml/path
/model

model
  nameModel2/name
  pathAircraft/myplane/Models/model_2.xml/path
/model

animation
  typeselect/type
  object-nameModel1/object-name
  condition
...
  /condition
/animation

animation
  typeselect/type
  object-nameModel2/object-name
  condition
...
  /condition
/animation

/PropertyList


So you import the primary model 'mymodel.ac (or whatever) in the path
(this could be a null model), and specify two submodel imports and two
selects that determine when the submodels appear.

Then each submodel XML file will reference its model:

?xml version=1.0?
PropertyList
pathmodel_1.ac/path
/PropertyList


Hope this helps,

-Gary aka Buckaroo

Well, in this case I should have tested with 2.8.3, which I don't
happen to have checked out. Anyway, we chose a simple branching model,
http://nvie.com/posts/a-successful-git-branching-model/ , where fixup
work done on the release branches is merged into the development
branch. It is very messy to have a commit virtually checked in on
several different branches. As there is no good reason for the
development branch not to have all the commits made to the release,
the commits should originate on the release branch and be merged into
development.

Now, you don't have to work this way locally, and in this case I
didn't; I had next checked out, so hacked away on a fix and committed
it locally. I then rebased that fix onto the release branch, tested
(hah!), committed that and pushed it to gitorious. I then reset the
next branch to blow away my commit at the head, merged in
releases/2.2.0, and pushed that. You can use git rebase to get
things in shape before committing to the master repo in the way I've
described.

Thanks Gary,

Worked perfectly ... turns out I don't need to specify a global model ... I
can just load submodels and give them names and use them.  A global
offset/rotation does work.

Now I'm having trouble with that whole ambient/diffuse thing and my model
surfaces that aren't pointed at the light are all black ... this is a 3ds
model ... is there an easy way to patch that up?

I've figure out about 0.01% of blender ... and so far that hasn't included
material properties or object hiearchies.

Thanks!

 So you import the primary model 'mymodel.ac (or whatever) in the path
 (this could be a null model), and specify two submodel imports and two
 selects that determine when the submodels appear.

 Then each submodel XML file will reference its model:

 ?xml version=1.0?
 PropertyList
 pathmodel_1.ac/path
 /PropertyList


 Hope this helps,

Hi,

 
 Curt has it right. Get real guys. No one is going to sue a
 non-existent
 organization with no assets. The worst they will do is tell
 us to desist.
 Which we will do of course.

Red Bull is an austrian company, and very famous among RC-model-fans.
In many german forums I found discussion about using their logo. And really 
many people there told that they are told by RedBull not to use their logos and 
marks. 
There have been even some people which have been sued by RedBull. And I'm sure 
they find their way to sue the author if they want to do it!

And indeed it would be better to keep off the hands- I do know that one of 
their active heli-acrobatic pilots is quite aware of the Project FlightGear.

Ask RedBull if we may use, if not- well, there are other nice liveries out 
there waiting to be made.

Cheers
Heiko

 Hi Henri,

Hi Andreas,

had a look at the patch you suggested on the JSBSim list
(http://sourceforge.net/mailarchive/attachment.php?list_name=jsbsim-develmessage_id=4D5436B3.10606%40web.decounter=1).

However, I looking at the code it seems calling these InitMatrix in
the FGForce constructor shouldn't be necessary. The FGMatrix33
constructor in fact does initialize the matrix to 0 (see
FGMatrix33.cpp, i.e.
FGMatrix33::FGMatrix33(void)
{
  data[0] = data[1] = data[2] = data[3] = data[4] = data[5] =
data[6] = data[7] = data[8] = 0.0;
}

. And the FGForce constructor will automatically call all its members'
constructors.

... Oops, wasn't finished typing... :)

Anyway, you maybe you can double-check if that patch really changed
anything concerning initialization. If it really did, then I suspect
there must be something else going terribly wrong (memory
corruption?), which could explain why the FGMatrix33 constructors
weren't executed properly.

I'm not siginificantly familiar with the 3ds format-- it might be

Is conversion to another format like .ac an option? If so and the

Hi Gary,

I think I've beat the model pretty much into submission now.  I was able to
export as .ac, but the scaling was off by 2.54 ... hmmm where have I seen
that number before?  I figured out how to scale and reposition the model in
blender wow! and there was much rejoicing. :-)  Then all the faces were
totally faceted so I figured out how to smooth the surfaces in blender
wow!!! three exclamation marks on that!!!

That got me to the point where I could manually edit the material
definitions in the .ac file and setup the ambient and diffuse properly, also
got the tires back to black ... and rescaled the textures  3000x3000 is
probably over kill.

So I'm learning more about blender than I want to know ... and I hesitate to
even say this because in 2 years some guy in some far away land is going to

Hey everyone,

Based on my (brief) reading of some United States statutes, I would suggest we 
can continue using these trademarks until asked not to do so. I don't think 
this will bring forth a lawsuit, most likely a cease and desist action which is 
easily complied with, if it is on trademark grounds. However I would definitely 
suggest whenever we do use trademarks we should publish a notice we are not 
affiliated, connected, or associated with the companies whose trademarks we 
use. I think we should also be cautious of the screenshots we use to advertise 
the software.

To throw something into the mix here: 
I've actually got experience of dealing with RedBull regarding the use of their 
logos and IP in Flight Simulation. 

Several years ago I contacted them for an old Payware project and they were 
most supportive, provided an email stating that as long as nowhere we claimed 
that they endorsed the product then they saw it all as good publicity. 

I'm sure they'd do something similar here, as would many companies. 

In fact there is only two companies that I'm aware of, who have caused issues 
in the FS community, that was a large American airline who requested a VA stop 
using their name, and got quite aggressive about it, and a well known Bizjet 
manufacturer who flatly refuse to grant any permission for any of their 
aircraft to be represented, and will go to great lengths to stop people making 
a product out of it. 

There's lots of history of probably most Aviation related companies being 
contacted by FlightSimulation enthusiasts/3rd party developers/ etc over the 
past few years and getting very positive results for doing so, in some cases 
huge gains as well.

Oddly enough that's kinda how I got into my current position. I used
to be a coder but played with 3D work on the side and advised grad
students and professors at work from time to time, doing the odd model

According to many RC-forums, they don't do this anymore as they licenced their

special thing: ask, and wait to see what they say. 
I'm sure they'd do something similar here, as would many companies. 
No as they licences their logos and colors to certain third parties. If you

 Hi,
 
   The Red Bull livery has been removed from this release.

Jack, thanks for caring and removing the livery from the package. As I said 
you can still provide it separately from your web site. This does not make it 
legal but moves FlightGear out of the focus.

 I find it ridiculous and a bit immature how Oliver people whine about
 a simple logo.

For the trademark owner (which happens to be Red Bull) it is more than a 
simple logo. It is identification, cult and trend and it is worth money.
So they are pretty picky who to grant usage rights.

 If Oliver really cared about preventing fictitious lawsuits as he
 claims to, he would concentrate his efforts on the several red bull
 logos that are already in our database.

These are two different steps to take. First secure the area from more risks to 
come in, then remove the existing ones.

There sure should be a debate how to deal with the ones already existing and I 
am glad you found the others.

 If this thread is further interfered with, I will be forced to result
 to more forceful methods of having my work committed, or I may very
 well change the license back to the CC license and our community will
 have missed out on a very high quality aircraft.

I am surprised that you still think this has something to do with the 
outstanding work on your aircraft.

as it's not yet released, what about changing licence to something alike CC 
etc.(see the forum) Android uses Apache licence...I didn't read those but am 
sure that there's one to keep off jerks.

i doubt...have a look at FSX. Even commercial products alike xtraffic etc use 
such liveries.

I can dish out links all day if I have to

And go ahead, get them removed. ;) You know what you'll have accomplished when 
you're finished? You'll have deleted hundreds of hours of work, all in paranoia 
of a lawsuit that will never happen.
Unless you wish to delete nearly all our liveries, all of you that do not wish 
for my work to be committed are being well, hypocrites.

On the subject of my AH-1; I have removed the content for now, what other hoops 
do you want me to jump through? I'd like to see somebody commit it relatively 
soon, so my (somewhat) recent work can be included in the release.
