Funny. I just tried to call a friend via GTalk. he has an N900 with PR1.1, too. The option for the cam didn't show up, I couldn't do anything else than chat or talk. Then I tried between my N900 and my desktop computer running Empathy. I got a different user interface (it did have a part that would display the remote cam image - and a smaller place where I could see the image coming from my own front cam), but the video was non-functional. Black. Am I about to configure router settings again to help NAT traversal?*sigh*
