I could probably contribute a little test program using CamShift to
track the face position/tilt and feed that information out using e.g.
VRPN. That is fairly easy to do. I would connect it to the viewer, but I
am not that familiar with the camera code. Probably the simplest hack
would be to attach it to the Flycam code for the testing (instead of
using pitch/yaw/roll from a joystick, get a VRPN quaternion).

If you are interested in that, contact me off-list.
