Yes, I am going to try to get in touch with him. They noted the possibility of using a tablet device with a single screen and two lenses, but I think they could do better. Thanks for the heads up!
Get that sweet 5.6" 1280x800 Hydis panel that we are all playing with, it is the perfect size for the optics setup they have. From there, they can get a newer Android smartphone that supports HDMI mirroring/video output (The Motorola Atrix comes to mind, and there are others), and mount it on the back of the board with the camera centered. Not only would that eliminate the jitter problems between the two units, it would also be higher resolution than what they currently have. Plus you could use the camera for walk-around augmented reality!
Now THAT would be even cooler than the setup they already have.
