That was not my intended usage, and would require a quite different
patch. Something like:
http://fixunix.com/openssh/175979-patch-controlling-remote-port-forwarding-over-control-path.html

The patch would basicly open up a dynamic forward port over the control
socket instead of having a listening socks proxy.
