I can confirm that the N900 can accept GTalk video calls including incoming video quite happily. Tested this with an N800 (speculatrix) calling my N900 over cellular and the N900 received the incoming video stream fine. It was only when I tried to send video stream back that the whole thing went pear-shaped. The audio was choppy but that might have been the cellular connection rather than the codec.
