sorry to burst your bubble.

There is no good audio or any video for Desktop Linux. There almost never will be for N810. People commenting on this thread will make no difference. There are no "developers."

Fring might do it, Gizmo might do it, Pidgen might do it, but I highly doubt it. I think you can try with meebo, and that might work via their internal flash chat. But yeah, its not going to come.
