We have adjusted the firewall to allow iChatAV to create audio and video conferences. I was able to successfully get connected to my machine at home from my machine in the office via an audio chat. How well it works will depend on network conditions, but I know it should at least get connected ok. I was not able to test a video chat since I don’t have the right hardware at each end, but I assume it should work. If it does not appear to work for anyone, I would like to hear about it.
iChat AV video works swell. Boo yeah! Thanks Dan!
