theoretically, someone from inside a secure network could tunnel out (ala Trojan) to punch a major hole through a 
firewall.  Am I understanding this correctly?


Yes, with the unstated caveat that you need a server on the outside to
complete the tunnel.  No biggee, but it makes it easy to find the otehr side
of the tunnel.

Besides, you could do this with http_tunnel for the longest time. This is
just cuter.
