I think a much more interesting protocol to have in the kernel would be Bell Labs' IL. It's implemented in Plan 9, and they say they are very happy with its performance. It's a sequenced packet protocol, ideal for NFS, CORBA messages and pretty much anything which currently either implements its own out-of-order + retransmit strategy over UDP or puts packet boundaries into TCP.
There's a description of the protocol at http://plan9.bell-labs.com/plan9/doc/il.html I have the barest bones of a start at a linux implementation of it, if anyone wants to collaborate :-)
