Curiosity question: what happens if I disconnect my machine halfway through a direct transfer? Do you support continued download/upload (or multipart)? I guess in the case of a connection to your server, presumably the receiving party would never know that you sent them something (until a retry upload happened). It's just that in the case of a direct p2p transaction, it's quite likely that the downloading user's downstream bandwidth is low, such that the chance of a failure happening over the entire course of the longer transfer is higher.
