The Apple airport will support two or three streams of video for a quarter
screen (320/240) - I have tested it. My guess is that it will support more than
a hundred audio users (at 10K per second). There are other solutions available
that could support more video users. I don't think it is a good idea to go
wireless in such a situation. Hardwiring and going 100BaseT switched would be a
cheaper solution and offer full-screen video as well.
