    You can tell if they're running old firmware revs (the one that lets
in both udp and tcp for instance) because it will give you the "beaker"
gif on port 80 on the outside.  I kinda miss the "beaker" gif... :-)

There may be other fun possible on these that I haven't explored fully

on a public list. :-)

E-mail me offline if you are stuck and you absolutely need to crack one
and are willing to spend some dev time on it.

P.s. has anyone poked hard at their SNMP?
