I wonder if anyone else has had any similar experience with iChat 4.0.2.
I am trying to screen share another machine over the internet (I have got it working on both machines behind the same router). I can get Video and all other functions to work.
I have screen sharing enabled in the ichat video menu and in the sharing preferences.
Imagine it's a router issue - but not sure what ports are needed to be open - at least that are different to the video...
