Will anybody volunteer to help me map what can and cannot be done between Mac and the rest of the world?
Let's take the case of a fully kitted Mac user with Panther and iSight and an XP user with MSN, Yahoo Mail, AOL, and NetMeeting and a basic USB webcam. If the user is in France he may also have Wanadoo instant messaging which looks like a shell that sits on top of messenger.
Case 1: Text messaging
Case 2: Audio messaging
Case 3: File sending
Case 4: One way video
Case 5: Two way video
(I assume that there is no case 6 around application sharing, whiteboarding, etc as can be done on JetMeeting).
Who wants to start?
