[This is now in the clustering section of the FAQs:

Although we *could* do this, we don't, because it's too expensive.
This would mean replicating every message across the the network in a
synchronous fashion. And not too many *really* need it, in the event
of a Rabbit node crashing, they just replay the log for that node.

BBHoss started a discussion about this on IRC (look for the discusion
about HA and DR between BBHoss and hal):

Having said that, this may be a use case for pluggable queues, for the
avail-o-nados out there :-)
