So I stumbled upon this video chat client that Collabora is developing called Muji. http://telepathy.freedesktop.org/wiki/MujiDemoClient
Looks very interesting. I didn't get a chance to look it over today. I'm going to open up the source code first thing tomorrow. So far it looks to be Linux based 4-way video chat.
For the uninformed: the OVC team is being funded by a research grant this summer to develop a cross-platform Open Source, Open Codec video chat program. If you'd like to help in any way please let us know.
