I only had enough time to whip up the quick demo here. The responsiveness is pretty tight as far as latency goes - it "feels" like the photo on screen moves in tandem with the one under my fingers. No perceptible lag. I wanted to try out some more interesting demos. One idea I had was to run the HexGL racing game (http://hexgl.bkcore.com/ http://hexgl.bkcore.com/) on the endpoint, and then have the app on the phone interpret the gyro as steering and send it over to the endpoint. However, I found that WebGL on the pi is slooooow, for both Chrome and Firefox. I don't think this is a raw power issue so much as using desktop browsers on a mobile device, where the browsers haven't been compiled with driver support for the graphics chipset (the Pi can run Minecraft just fine, so it should be able to handle a simple racing game). My educated guess (from just the photo-viewing demo) is that the latency is good enough to support responsive gaming input.
