This makes me wonder whether there's some relatively simple configuration of cameras that can be used to give a basic 3-d type experience. Nothing crazy like the oculus, but maybe something where a computer can use head tracking so that as you move your head, you see a little bit around the other person's face so it feels a little more lifelike. I assume this would only be relevant for the primary speaker, of course.
