Brian Reid has a nice algorithm for handling this in his archive
server -- basically, the more a user requests from the server (within
a certain quantum), the lower the priority of the request (and thus
the longer it takes for the request to come back).  The size of the
requests pending for a user is inversely proportional to the priority
of the requests.  This quickly stifles people (intentionally or
unintentionally) trying to flood an archive server.

Still, lots of people making lots of requests could be a problem
(Brian solved this by allowing the server to queue up lots of
requests, but only to service a certain amount within a day, based on
the priority scheme above).  This nicely smooths out the overhead of
running the server...
