we have been amazed how much people love the bump interaction. lots of people bump just to see it work and then don't transfer anything. most mobile wlan chipsets (including the iphone's) don't support adhoc (so would need router) and bluetooth sucks, it is inconsistent and unreliable (even between identical phones).
