Hi Lisa.  I see a lot of folks have already given some great advice on this and 
there's not much more I can add!

I just want to make sure that you're aware that OpenSimulator is still a platform in its infancy (as is the whole area of educating via shared environments, I think). Therefore, there are still a large number of unexploded bugs, missing features and performance issues around, though OpenSimulator continues to improve over time.

I'm also sure as a previous MMO developer that you're aware of just how complicated these platforms can get and the aspects of ongoing maintenance costs, cost of content creation, etc., though I would say that aspects of these are vastly cheaper on OpenSimulator than on other exclusively commercial-oriented platforms, both self-hosted and with third-party providers.

Having said all that, I think we're just at the point where some very interesting things can be done and there are many educational institutions already involved/experimenting with OpenSimulator (e.g. PLANE [1], New Worlds run by the Chester County Intermediate Unit [2], ScienceSim from Intel [3] and lots of others).

I would also urge that anybody considering funding viewer development talk to the existing viewer projects first before forking. These are produced by people who have already shown a long term passion for exploring the virtual world/shared environment space and it would be great to see sustainable projects catering to OpenSimulator in this area).

Hi Maria,

Thanks for all this information. I should have written more about the scheme I 
am writing a proposal for, rather than
just link to it.

If this proposal is successful, the project will be funded up to $400,000 AU 
over three years, (and hopefully more
funding after that, but otherwise we would have to find another source). Also, 
projects funded under this scheme have to
be free for educational use within Australia, and they have to make use of the 
National Broadband Network, which is the
very high speed broadband network our government is building Australia wide. 
Part of the reason for the education portal
is to show it off and justify the expense!

So the only hosting solution that would fit all the requirements would be to 
build our own servers locally, so we get
the highest speed possible under the NBN. And we could afford to pay the 
programmers/tech heads needed to set the
hosting up, and run it for at least three years.

The project I have in mind is a bit bigger than just what OpenSim can provide 
under normal circumstances, and we would
want to maybe fork one of the viewers out there and add some new features to 
it, using part of the budget. Hopefully
what I'm intending would be useful to other educators and if the project wasn't 
funded beyond the three years, the
development of the new viewer would continue (of course it would all be open 
source). The features we would add would be
specific to teaching history through virtual worlds, and teaching in general.

So I would love to talk to someone about my original questions regarding 
structuring historical sims that exist not just
in three dimensional space but also back and forth along a timeline. I've 
studied a fair bit of general relativity back
when I was doing my physics degree, so I can kind of handle thinking in four 
dimensions, but this is still a bit tricky,
lol.

Sarge -- Thanks for the kind words!

Lisa --

Here are my recommendations, in order of difficulty:

1. Easiest and cheapest: go to http://www.kitely.com and sign up for the free 
six-hour introductory month, which comes
with a free region. You will be asked to download a small plugin, then it will 
automatically install a viewer for you,
create your region, and take you in-world. Easy, peasy. You can practice 
building, or upload any of the OARs available
free to educators to start with.
Check out: 
http://www.hypergridbusiness.com/2011/06/where-to-get-content-for-opensim/

If you like it, $35 a month gives you unlimited use of Kitely, plus 20 
(twenty!) regions. You can add extra regions
for just $1 a month each. Each region can hold up to 100,000 prims and up to 
100 simultaneous visitors. (No kidding!
They run it in the Amazon cloud and the scaling is excellent.) For educators, 
it's the single best deal out there.
Here's the downside: your visitors will get two hours a month free (six hours 
the first month) but after that they
either have to sign up for a plan or pay 20 cents an hour for usage. Or you can 
opt to pay for their usage.

Let's compare this to the Second Life deal, with $300 a month per region, and a 
$1,000 setup fee. For the $300 you can
have something like eight users with unlimited use accounts (you, a couple of 
fellow teachers, the students doing the
heavy building) and 8x20=160 regions and you can put the $1,000 you'd otherwise 
spend for a setup fee towards 300,000
minutes worth of access time for visitors.

If you ever want to leave Kitely for any reason, you can export your entire 
regions (terrains, objects, scripts,
everything on them that you have rights to) with a single click, and import 
them to anywhere else you want in a couple
of minutes. They have Vivox voice (the same as Second Life), mesh, 
media-on-a-prim (to put interactive Web pages and
videos on in-world surfaces) and megaregions. The only thing that's missing is 
hypergrid, and that's coming with the
next hypergrid security update. They also have bots -- aka NPCs (non-player 
characters) -- which you can use to create
robots that simulate historical characters and interact with your visitors.

2. Easy, a bit less cheap, but more options: go to Dreamland Metaverse 
(http://www.dreamlandmetaverse.com/) or one of
the other vendors in our hosting directory: 
http://www.hypergridbusiness.com/opensim-hosting-providers/ I particularly
mention Dreamland because they have an excellent reputation with educators, all 
the latest OpenSim features, and are
currently running the grids for a school district in suburban Atlanta. They can 
set you up with a private grid, or
land on any of the open grids out there, including OSGrid. They can set it up 
so your teachers can hypergrid teleport
to other grids, and your students can't. They can automatically create user 
accounts for all your students and
teachers at once -- and there's lot of other custom stuff they can do, as well. 
They have moderate prices -- they're
not the most expensive by far, nor the cheapest, but have a good reputation for 
reliability and service. And whle
Kitely regions are only up when people are on them, and are put to sleep 
otherwise, Dreamland regions are up 24-7.
While this means higher prices, it also means that visitors don't have to wait 
for a region to boot up when they first
teleport to a sleeping region, which can take a minute.

3. Not easy at all, but free. You can run your own grids on your own servers. 
You will have to set up a MySQL
database, and an Apache server, and the OpenSim server, and keep all of those 
patched and updated and regularly backed
up. The easiest way to do that is to use New World Studio -- 
http://nws.virrea.fr/ --  which installs all of those for
you automatically. You will still have to learn how to use the OpenSim 
management console, however, and, unless you
hire a consultant, if you want to manage users or inventories or terrains or 
OAR files you will often have to go to
the server console and type in server commands. The commands are here, to give 
you a taste:
http://opensimulator.org/wiki/Server_Commands

If all your visitors are local -- behind your school firewall -- then this will 
give you the fastest possible
connections, since the OpenSim grid will be hosted right where the visitors 
are. Some of the OpenSim hosting companies
will do by-the-hour consulting for you, helping you set up your first grid and 
installing and configuring routers and
viewers and all that other messy stuff. And you can have as many regions, prims 
and simultaneous visitors as your
network can bear -- which could be quite a lot, depending on your 
infrastructure. And if you want to allow remote
logins, or hypergrid travel to and from other grids, you will need to configure 
it for hypergrid connectivity, and
punch a hole in your network's firewall to allow the traffic to go through.

Feel free to contact me directly if you have any additional questions!

Best,

-- Maria
