Richard, the real problem is that most of the problem clients are not
running software like the NTP reference implementation but clients
written by people who didn't understand the rules of proper NTP usage
and heavily abuse the servers. Many of these seem to be Windows clients
and if you think that anyone is looking at what it's doing, I do have
this bridge for sale...
