At last!

I tried calling the N800 from Sightspeed on the PC and I actually managed to get all four windows working properly for the first time! The N800's video quality as seen at the PC is terrible, but the PC's video window on the N800 is very smooth.. this was after trying Sightspeed on the Tiger partition MB1. Little Snitch kept popping up asking for low level OKs, such that it timed out once before I could sort it all out :(

So theoretically one could use the N800 to talk to some Sightspeed users, but the quality makes it not worth it...
