Interesting. While I'm not enthusiastic about "augmented reality" etc., I think this could be put to good use in an MMO. Imagine in something like WoW if you could chat and see the facial expressions of the people you were talking to (or their Avatar's depiction of them).
A game I'm developing with some friends:

It is largely a technical exercise but feedback is appreciated.
