OpenSSH has both SSH1 and SSH2 protocols, use SSH2 protocol (setup the
config file for sshd to use SSH2 protocol). This should do exactly what
you want. If you login using a Linux box (or a win box using an X server)
you can even open X apps on your desktop. Most (if not all) processes you
start on one node will migrate to the best node available.
