Hi Carel, this is a rather complex question with no simple yes or no answer. You can use the dialog module with no "in-memory" storage of dialog data and leave it to the database to do the replication. I think postgres has Multi-Master Replication, i am not sure about MySQL. At a major german telco operator, we did something similar: We had two servers, both with different addresses and an Alias for the other server. In that case, we had two loadbalancers (logically one in a HA setup) in front, who would do the failover in case. Worked fine.
