Perhaps perdition as well. For POP hosting read/write would be fairly even I'd imagine. For mysql clustering isn't really an option I don't think yet, as you are limited to ram tables only so you would need replication. But replication + ultramonkey looks a whole bunch like a HA cluster to me. Perdition for load balancing by moving users around to different "clusters" of dbmail.
