If you are ever in LA, you should come to a LAPUG meeting. One of our
members also replicates over long distances. He is replicating from
California to China using a highly configured slony in combination
with other software. His software analyzes the possible routes he has
to find the routes with the best latency. He has configures a
revolving Master-Slave replication.
Perhaps you guys to share notes?
