I would assume any added latency is negligible -- the sensors + interpretation + rendering should be very fast. But you've still got all the network latency including Wi-Fi latency on both ends. And you always need a small audio buffer so discrete network packets can be assembled into continuous audio without gaps. So I wouldn't expect this latency to be any different from regular videoconferencing.
