I apologize about the non-croquet post, but thought this will at least
inform what others are up to. Anyway, I found a video that gives a
pretty good idea what Sun's business collaboration oriented virtual
world MPK20 is currently like.
It was interesting to hear that the app collaboration was just screen
shots, thus in the concept phase. The video cam thing is interesting.
From my reading elsewhere there is probably a sun virtual presence
computer on the other end. So the moving of the "live view" is
panning a webcam attached to a small form factor PC / laptop.
