I didn't know about this protocol before, thank you. It seems this
wheel is constantly reinvented.

It wouldn't compare to SCTP. It would make the adding of SCTP support
to ASIO much easier hopefully.

For my client's purposes, SCTP is not useful because it is not TCP
nor UDP, and therefore is not understood by home networking
equipment. This is a showstopper for them. There is SCTP over UDP,
however there is no mature portable implementation library for that
which I am aware of. In comparison, UDT is portable and has a mature
portable implementation library, and one in fairly high quality C++
at that too. Hence the choice of UDT over SCTP as the second wire
format we are likely to implement.
