Agreed, AMQP like routing can be very useful. Initially there will
only be native support for 1:1 and pubsub, but it is trivial to add
more sophisticated routing to 1:1 by writing a worker to pull messages
and reinsert into other specific queues (replication can be done this
way too). Once we have a solid foundation I certainly want to look
at providing this functionality closer into the core for performance
reasons (basically built-in router workers that you can control via
an API). So, yes, but not for version 1. :)
