I just got an email from someone I talked with from apple at nab about the set up.
of course we know that the 2 producers have there own computer with i chat.
The editor has his own computer that he has running his I chat camera and the fcp program. He has a second computer tha that is set up to recieve the output of fcp and used as an ichat camera. Out of the computer that is running his i chat camera and the final cut program he is running dcd out dvi to s video into a dv converter. he is also running a second audio out line that can be digital usb etc into the dv converter.The dv converter is then pluged into the mac computer that is setup as the fcp output I chat station
Hope this helps
