[Twisted-Python] Multiplexing multiple transports over one

[Stefano Masini]

It shouldn't be too difficult to implement, or maybe it's already there...

I'm looking for some mechanism that allows me to multiplex multiple
protocols over the same connection. Say I open a socket on port 3000,
and I run both http and smtp over it. Of course this is sort of a port
redirection thing, like ssh does, so I need a way to specify which
host and port should be contacted by the other end of the tunnel.

It looks like consh.ssh.forwarding should do exactly this, but since I
never used it, does it only do it over ssh? Or can I use it over a
simple tcp connection as well? I'm worried about the encryption
overhead.

thanks!
