Be careful about multiplexing different qualities of traffic over a
single TCP connection.  You don't want to have the SSHv1 flow control
problems all over again.  You also don't want to replicate SSHv2's
answer to those problems.

Basically, you should want one connection for bulk-ish traffic, and
one for non-bulk-ish traffic.  Else bad.
