It looks very cool, but I must say I'm skeptical about their claims about the latency. Judging by the video, it's at least 200ms, perhaps as much as 500ms. Contrast this with John Carmack, who has recently talked about the importance of low latency for an immersive experience. And Carmack talks about the impact of just 1 or 2 frames of lag, which is the equivalent of 3 miliseconds!
