	Harlan is not the criminal here.  Harlan doesn't have a tool that 
does a traceroute from his server to the IP address of the web 
browser, then does an ntpdate command against each of the IP 
addresses that show up.  Tim Hogard has that tool, and apparently has 
had it since 1995.  If you want to yell at someone, yell at Tim and 
not Harlan.

	What Harlan is trying to do is open a wider discussion on the 
possibility of NTP protocol enhancements that might allow us to do 
local auto-discovery of proper NTP servers, in accordance with the 
access and usage policies of the individuals or organizations that 
own the devices in question.  I think this is a good subject to
