One of the best features in drizzle for me is its flexible replication, i built rabbitreplication about a year ago which replicates from drizzle to basically anything over rabbitmq.
We do plan to work on things like Rabbit and Tungsten replicators soon.
In the mean time we recommend the native solution which is similar to MySQL's master/slave but uses the GBP messages stored in an InnoDB table.

* note that rabbitreplication needs a bit of love to actually work since the GBP messages have changed since i last had time to update it.
