Watched that making of avatar the other day.
Found it Ironic that the bodyskins with the digital sensors and diodes on the suits made it possible for RL people to control 'avatars' of themselves on a computer screen.
So yeh, hard yards are probably done.
They are? Or are you asking based off our earlier comments? If the latter, we were just surmising to the possibilities of it happening.
If the former,... How cool!!
