If it is the product I was told about, I don't think it supports multicast
video conferencing. You pretty much need MC if you want to effectively
VC with a bunch of different sites and not consume your entire bandwidth.
Not everyone's network supports MC, but you can always use a MC bridge.

No, I don't think so. They have a complete VC package there for their
conference room, so that was well equipped last time I checked.

UTHSCSA doesn't have an installation, per se. What we have is a
venue server on a multicast gigabit link with access to Internet2
that allows us to host any number of simultaneous conferences.
We also have our own mobile node that we can move into any
conference room and set up for AG conferencing. We also have our
own MC brige, thanks to Jeremy.
Several departments at UTHSCSA have their own conference room
equipment for VC, but most people probably use personal nodes (usb cam +
microphone/headset without any echo cancelling equipment) directly from
their desktop/laptops. I routinely use such a setup from home when I
don't feel like coming to work. Jeremy and I use this all the time. I
also use such personal node to VC an entire workshop which is taught
monthly - from the comfort of my office, with participants all across
the US and Europe.

Hey, maybe you could set up a demo for these guys with us, and we can
demonstrate some of the really cool features (high-dev video streaming,
VC recording of all audio and video streams, etc. and convince the
guys to take a second look at this outstanding freeware package from
Argonne National Labs (developed with NSF funding). This is how we
got our IT people interested in it, just give them a bunch of demos.
Even if you don't want to set up your own venue server, it's not
a problem, you can use any of the public servers, like Argonne, and
simply reserve a virtual conference room, or just use ours. We have
a gig link up to Austin, so that's a whole lot more than you would
ever need. Ahh, and it runs on Linux, Mac, Windows, and other Unix
platforms. It's mostly written in python.
