Mr. Tricks: I'm not sure what to tell you about UDP, but I know TCP is designed for reliable data transmission. It can guarantee that the message gets to its target, but would probably cost alot in speed, when packages start getting lost. UDP is more targeted for speed, where package loss isn't all that important, but speed is.
Plus, I believe Blitz will actually pause your entire program to initiate a TCP connection.
As for how DirectPlay works, I don't really know myself.
