This topic is very interesting to me, so please keep the list updated! My previuos experiments (not DBMail-related, I must say) with NDB wasn't really good. I tried to "clusterize" a standard application without very good results, so instead I switched to standard circular replication + auto_increment_offset to avoid key collision on a standard InnoDB backend and, nowaday, keeping finger crossed, had no particolar issues.... but I'm VERY interested in your tests!
