Of course, Dropbox can't prevent people from sharing content out of band. But if Client A and Client B are offering arbitrary byte ranges to complete strangers, they are effectively playing BitTorrent again.

Yes, but they are only exchanging a constant amount of information to fool the server challenge, whereas we could hope to do better if the server builds challenges which use information that he knows the client has.
