  This from an unnamed source since I don't know if s/he wants to be
credited/blamed:

| Why not build a "discard server" which listens for broadcast discard
| packets of that form and reflects them back at the discard port of the
| sender, thus causing a license collision, disabling the product....
| 
| Needless to say, you only want one of these on a network :-) 

  Hee hee.  I really like this idea.  I'd get in all sorts of trouble,
but it would almost be worth it ... :-)

  Obviously any such Anti-License Server would have to be programmed to
handle all the other similar schemes running around ...  (For example
SCO's XENIX TCP/IP runtime broadcasts packets to UDP port 60000 every
thirty seconds. (And yes, we've complained that 60000 isn't registered.
They should obviously use the [currently nonexistant] License Multicast
Address (LMA) to UDP port 9.))
