This seems like kind of a crummy thing to do to snapchat, but I like the idea.<p>I wonder if that could be successful, like a file swapping service built on the same premise of one time only. Charge a nickel a shot or something. I have no idea why that's useful, but for some reason I think it's cool. Maybe just because it's set and forget and you don't have to worry about cleaning up later.<p>Does anything easy to use do that already?
