Hmm, at first I saw the title and thought it was an app that would make cheating on tests in class easy (think like the blackjack counting app - could do something like "put the phone in your pocket and shake your leg N times to ask for help with #1, and then get M buzzes back to indicate which answer from fellow students"). I don't condone it, but I bet it would sell well if implemented cleanly. As it were, this is also a cool app. :)
