This does have several advantages -- no head-of-line blocking,
and datagram-level control of sending queueing latency. I'll
take a look at the retransmission protocol I-D's to see if
there are any compatibility issues ... 

However, for general-purpose use, there probably needs to be
a way to run MWPP over TCP, too many people ask me about it
not to support it. There are some WAN music projects that are
comfortable using TCP for their audio work, and would add 
MWPP support if it can easily fit into their TCP code ...
