Six Feet Up is running RelStorage + MySQL + async replication for one of their customers. AFAIK, it works well. Also, I expect the new replication features in Postgres 9 to work well with RelStorage. Depending on what you're doing, balancing between data centers could be very complicated. You might start simple by directing traffic to only one data center at a time.
