I am hoping to do a video conference between 4 other groups plus ourselves when Tiger comes out. But iChat is limited to 3 + us for video chat, right? I guess we could do an audio chat if we had to but it is not optimum. This is for a Parkinson's disease support group outreach program. Our doctors would like to be able to talk to four support groups at once and answer questions from all four. If we could have 4 + us on iChat video at once, it would be perfect. Thanks!
