i consider SCP/MUX to be another transport layer... and in the context of
doing RPC over HTTP it's really beneficial in that it gives two packet
request/response.  in many cases you get the ACK piggybacking as well
which cuts packet costs roughly in half.  i don't really see this as a
fault of TCP -- TCP does its thing well, plopping SCP over it lets two
servers communicate efficiently at scale.

gotta remember this is at scale with lots of parallel streams going on.
