It's very cool tech and I can easily imagine it taking on lots of forms in gaming. Even the most hardcore of the games I run on my machine (Planetside 2) doesn't really use all the cores of power, nor scratch the memory. There is plenty of oomph left in the box.
Where I think these technologies might struggle (at first) is where bandwidth is low. Lag can be very jarring in human-to-human communication. I think people mind less when it's a Skype call (or Hangout) but when there's a facsimile in the way, I think it might be a bit more odd.
Constantly paranoid about pc memory (my last "L337 R1G" long since past), I run Hangouts from a separate machine than the one I run the online gaming table on. I could see this coming in very handy to set mood and differentiate between NPCs.
When all you have is a gun that fires windows, every problem looks defenestratable.
