I think the people flailing their arms and dodging virtual stuff is not going to be the main use though. I could imagine several less-intrusive, very useful things. Go to an airport/train station etc.. and have a user-specific glowing arrow showing you where you need to go next. Go to a conference and have a social network overlay telling you everyone's names and what they do. Or Sims style public intent-bubbles - say a waiter surveys the restaurant and can see who's ready to order/pay.
