Uuh... that would be extremely hard to do. It'd be pretty cool, but it would more than likely require it to simultaneously record their view as they play, and then show you part of it. The code would be a mess, it would probably take months to script, and the recording... well, I don't even know if that's possible. However, there is a killcam that orbits them. I can probably make one see through their eyes,(by looking and Event_CameraControl,) but still. The way you're saying it... probably not possible yet.
Edit: Oh god, nvm. That looks pretty hard. (considering I would need the right offset for where the face is, ntl the direction. Well, the direction should be... fairly easy... but the offset wouldn't.)
