doug, i still disagree. i know from friends that the DPRIV WG is working
on a new port number, that won't be subject to TCP/53's problems, and i
wish them well. meanwhile UDP/53 can work (and mostly does) whereas
TCP/53 can be trivially DoS'd, and must never be depended upon. we can
revisit that topic in detail if you wish. --paul
