I tried a bit of a test with two players in Newcastle (300 km away). The video was sharp and smooth and the synch between sound and video was better than we have had with any other solution. You get props.
The player who is not a fellow beta-tester commented that account creation/signup was the simplest and went smoothest of anything he has ever had to deal with.
One fellow (running Chrome on a Mac) zoomed the map to 10% and then back to 60% and lost video: to get the video windows back he had to zoom to 10% again. But I couldn't replicate the bug (I use FireFox) and neither could the other guy (who also uses Chrome on a Mac). Go figure.
The players wanted anyone to be able to move the sprites representing chairs, murder weapons, etc.
We all wanted the video windows moved from the bottom of the screen to the top of the screen to be near our cameras. This is so that when we look at someone's video feed and speak to them we want to seem to be looking at our interlocutor, not averting our gaze.
