I totally agree regarding the implementation of the msg_store. I think that putting another database(MySQL, Redis, Riak) behind a queue could bring a severe performance problem. Having said that what do you think of putting a layer on top of the rabbit_msg_store that could add replication/clustering a la riak_core? So the idea here is to use the same storage backend that the variable queue uses but coordinating read/writes using riak_core. (Keep in mind this is not riak_kv the database known as Riak).
