   To Tony:  Are you saying that just because FTP, telnet, and Web don't 
   run over UDP it's not important?  I respectfully disagree.

I'm meaning that lack of support for UDP would not make a masquerade
scheme violate host requirements.  Frankly I haven't clue one about
how to implement UDP masquerade, never having so much as glanced at
the problem.  

To clarify another point:  I do not advocate a linux-style
implementation of masquerade.   I'm just too ignorant of the
alternatives to make a specific proposal, and too enthusiastically
supportive of the functional goal to keep my mouth shut.
A dangerous combination.

TCP is *more* important the UDP, though, for the preponderance
of "customers", that much seems obvious.  UDP is second-order.
