Essentially tip, but instead of presenting a tty, it opens a tunnel port that (for instance)
telnet can talk to. Example (on credit):

tiptunnel /var/log/tiplogs/pc1.acl telnet

Will open up a local port then fork/exec telnet with "localhost" and the tunnel port number as arguments.
(Functionally equivalent to "tip pc1", only with telnet escape sequences)

A later version of this program is what users will likely download for the quick-tip-through-the-web scheme.
