hi Gavin,
1) Single point of failure is one problem with Messaging middle-wares. How easy is to set up RabbitMQ for replication,load balancing ?
2) i worked on Tibco EMS in the past. For message persistence we used Oracle and during peak hours, sometimes due to high load, EMS used to stop working causing message clogging. What kind of message persistence(like KahaDB for ActiveMQ) RabbitMQ provides for fast persistence?

1) RabbitMQ has built in clustering and highly-available queues. Additionally it has built-in support via a bundled plugin for cross-datacenter messaging, including federated queues, which should do the trick.
2) The backing store for RabbitMQ is pluggable, so if the MNesia based tables are not fast enough, I know of a few backing stores to choose from including LevelDB and TokyoCabinet. I've not played around with benchmarking them to see what kind of performance gain one would receive in using them, but I imagine it's not trivial.
