Also, for this sort of thing where it is likely to be setup once and forever forgotten, there should be a packet-of-death. There *MUST* be some response for the central server to permanently tell clients to go away. This is absolutely necessary, otherwise you'll have no way to depreciate the service, either from age or from excessive load. NTP taught this lesson of this mistake.
