So if I connect to multiple ultrapeers, should I create both a TCP 
and a UDP socket for each one to handle the messaging? I'm currently 
just connecting with a TCP socket. I realize that UDP is not 
actually "connecting" but will need to create a UDP object that 
listens on the same port as the TCP socket I'm connected to the 
ultrapeer on.

Is this "extra header" or any other UDP protocol specifics documented 
online? 

I really appreciate your prompt replies and thorough explanations.
