Comment (by arma):

 A related but different idea: djb pointed out that we could use a few bits
 in the onion name itself to indicate how many replicas this onion service
 is using in the hsdir ring.

 That way it could be set on a per-service basis, rather than a global
 basis, so popular services could scale themselves better.

 (Problem 1: you need to predict your popularity at the beginning, when you
 choose your name. Problem 2: I am suspicious of any design where there is
 more than one "name" for the same service, since it introduces
 partitioning questions, caching concerns, etc.)
