Yeh for sure, should be fine, we will start small on the cams project
which only attracts a small audience then onto the VOD content which is
100's or thousand's of concurrent users.

Is there a current example of this atm to setup a VOD playlist stream ?
Im pretty sure there was one there i cant find again loading files from
a directory. Is there a way we could extend that for an xml playlist to
rotate playing the VOD content and then switch to the webcam url
playlist node when it becomes available. I see this might be the way it
can work, however how could the application load the stream from
another application point being for the webcam , if that made any sense
?

I see stuff about recording, it seems similar to what we need to do, i
think its via ffmpeg ??

I think i rephrased the question a little above, basically a server
side xml playlist loading files from within a directory on one node,
and then the next node is the webcam stream point which is switchable
somehow, but also not knowing how to access that webcam stream locally
on the server without having to give the full url , which the server is
then possibly trying to access itself via the www instead of via its
internals.

Ill consult the log4j docs, LogParser can handle other formats than W3C
also.

I'll probably revisit security concerns when we start on the VOD
project so ill return to this question later.

Yes, it is rather unfortunate, however we may be looking currently at
purchasing flex builder2 off them (unfortunately) as the plugin
versions dont seem to load on eclipse 3.1 on osx ;) I can still use the
free SDK compiler and ANT, but we need to build a broadcaster app
interface fairly quickly, so could lend on its designer, which will
interface with custom AS classes/packages etc. I will probably revisit
my previous workings with mtasc and swfmill however im nervy abouts its
future versions not supporting AS3 rather a specialized psuedo
language.

Ok ill revisit this question soon. Even just two servers loading VOD
content off a single VOD content server, might be sufficient rather
than applications on each server proxying to the main application on
the VOD content server and caching the requests, however caching might
be valuable also.

OK, not a problem, see Ive already begun to respect the people on this
list, as I got responses to a fairly detailed technical essay,
something not even the techs at adobe could bother to come up with.
I have extensive knowledge in the windows media side of things, aswell
as real streaming and quicktime so maybe if I manage to replicate what
most of them do into applications I could document it and also share
knowledge about what they do in general. However I hear there are
already modules becoming available to achieve most things the windows
media server is capable of.
