All sounds mighty cool - one question though:
Does this also make it possible to have multiple players on one machine?
Like if you have 2 or more gamepads or a pad and a keyboard? Obviosly
they'd share one screen and could walk very far apart but it's still fun
if you have friends round and they can just join in.
