Actually we may want to record the number of the channel in the protocol, but that's it. Other then that it requires changes all over, but small, and has been discussed before, just needs someone to love it enough ;)
I was thinking about a tunnel to the host, not to the guest, for guest 
console access, without having to configure and start ssh tunnels 
manually, outside virt-viewer/remote-viewer.

[that's right, if you want the guest console you connect to the host]

Having virt-viewer / remote-viewer setup a tunnel for the guest would be 
very usefull to get a bash prompt (not a console GUI) and transfer files 
using SFTP. But for now I want just guest console access.

The current windows port has only a barely usable remote-viewer. When I 
try to start virt-viewer, it complains missing libssp-0.dll.

And I can't make spice+tls work. :-( Using TLS requires extra setup on 
the server side, I guess the easier path for windows users would be 
having remote-viewer or virt-viewer handle ssh tunnels.

It looks like on Linux remote-viewer creates the ssh tunnel itself, but 
not on the windows port.
