	Regretfully, there are plenty of misconfigured clients which seem 
to gleefully ignore KOD -- this is Netgear/UWisc all over again, 
although not on the same scale, at least not yet.  Give the Debian, 
NetBSD, and FreeBSD people half a chance, and we may be.

	So, the pool.ntp.org project needs another way to get these 
people to stop abusing the servers, and the method being proposed by 
Simon is that we give them an "obvious" bogus time reference, at 
which point they hopefully decide that we're not a good time server 
for them and they go away.

	Having been on the timekeepers mailing list and seeing the 
traffic from the various pool member operators, I support the work 
Simon is doing in this area.  I wish there was a better answer, but 
so far I haven't been able to think of one.  I've been fairly silent 
on this topic so far because I haven't been able to propose a better 
solution to the problem.
