PTZ Control with Head Tracking for Video Chat

In a video chat, you usually can only send video in low resolution, because of limited bandwidth. On the other hand, your camera may well be able to record video in high resolution. So, should you scale the image down, or should you send part of the image. And what part?

I really like this idea to use headtracking for zooming and panning. This way, you can send only the zoomed and panned part of the video, which makes the best use of your available bandwidth.
