Ssh does it for you, or put a seperate compressing proxy into the system.
Thats how X handles it normally. It avoids the single thread/compress delay
problem in X - eg with dxpc.

For ssh you tell it to do a port redirect when you run ssh -> machine. See
the ssh manual page as it varies by OS how to do it (actually the commercial
windows ssh may still be lacking it - it used to).
