Right now it lives in the rack in fremont.ca.us that holds geocoder.us and
my/Schuyler's personal box; this is a good situation for it because it
is physically near Rich if it needs to be kicked or cosseted. 

I know jack all about database replication. ISTR mysql is easy to do a
master-slave type configuration but not peer-peer ... this may have changed.

Have you considered something like "sharding", like the MMORPGs have
to do when they get overfull? And synchronise the shards every N
hours. I wonder how complex this could wind up. A hard one, how much
complexity is necessary complexity? :)

Does any of the OGC prior art even address this problem, i wonder?
