As far as I know, the only way to do this would be to capture the video, encode it (on the fly), and stream it as an mpg over the network.
I'll try it right now and see if I can get it to work...
Edit: With the software that I have, the only problem I have with doing this is that I can't view the same mpg that I'm capturing on a different computer (can't have two computers using the same file at the same time).
