Yes, the model is essentially one of a central write-master with all
clients being replicas (using our own replication technology).  We do
want to think about moving away from this, however, possibly using
local proxy-caching with a handful of servers replicating from the
master with syncrepl.  It's all still to be investigated properly, but
there's certainly an incentive for that.

get these patches from Quanah's stanford page...
