Yeah, I should have mentioned I've tested n800 to n800 with success. However, I did experience some odd results (like the screen split vertically at one point) but I'm not sure of the cause. Do note that the webcam needs decent lighting for a decent picture.

Incorrect. That's just yet another hyperbolic statement. The issue I mentioned has more to do with the PC side of things, since Google lacks a built-in video capability. Note above that another user got Jabber video working.
