If it transits with different TCP ports, it'll work, if it transits in
same TCP port, I don't understand how it could work, but I'd love to
see it done.
If it's different TCP ports, you're losing benefits of the
ControlSocket, as you need to do new 3way handshake etc (or multiple,
if that SSH connection happens to traverse many devices)?
