I'm assuming that the server has some intelligence so that when it 
gets enough load that it is sending out a lot of RATEs, it can go 
into a "panic" mode and start sending out KoDs to everyone?


On that same line of reasoning, do we want to enforce a mandatory 
exponential backoff for all clients during the initial volley, if 
they don't get responses to their queries?  This would help the 
clients automatically reduce the load that they present to sites in a 
UWisc-type case, and hopefully reduce the need for the victim site to 
be sending out KoDs to everyone.

Of course, this would have to be built into both the NTP and SNTP 
standards, otherwise most clients that would be likely to be 
misconfigured to cause these sorts of situations would not 
incorporate this feature.
