videobridge

I've explored with some people the idea of creating a "Video bridge" with open source buildign blocks http://www.dorfwiki.org/wiki.cgi?VideoBridge

Probably the best working example of what I would like to do is at http://flashmeeting.open.ac.uk/

I am right now assessing how to incorporate this into Drupal. Some open questions:

Whether to use Adobe Flash Server, or extend some other open libraries?

Is anyone else already working on this?

What would you like to see?
