I think it's somewhat doable already, it's just a matter of combining different technologies. The biggest drawbacks of a single camera setup are occlusion and missing depth information. Depth information can already be derived from a single camera video rather well, but occlusion is still a hard problem. There's no 'clean' way to get around it, all you can do is quesstimate. A similar problem I've been thinking of is tracking a (computer) player's head (or eyes) to get the same functionality that TrackIR has. It's a fairly controlled subset of the single-camera-motion-tracking problem and would be an excellent start: It would enable tracking with a single webcam, no additional HW needed.
