I use Cipe extensively for things like that, though I use xterms and
rlogins mainly. Even on 56K connections and over long distances it's no
problem. It should be faster and more robust then ssh.

You did not happen to deny ICMP on some of those firewall? Cauze that
will break things. Think about must fragment messages and the like.
