[erlang-questions] OTP Design

The new federation plugin ( http://www.rabbitmq.com/blog/2011/06/22/federation-plugin-preview-release/ ) for RabbitMQ definitely holds some promise to decentralizing AMQP and I've actually found the Erlang bindings for RabbitMQ are pretty easy and straightforward to use...if you like Erlang of course =)

They're pretty different. 0MQ is more of a toolkit for building your own messaging systems.
For centralized broker models, AMQP is great. RabbitMQ is very solid.
And of course it's Erlang. I have nothing but good things to say about it.
My problem with AMQP is that it tends to become a central architectural feature -- similar to the big, centralized relational databases. All of a sudden, you're feeding and caring for the broker
-- and if it goes down, it takes a lot with it.
AMQP is also a complicated protocol, which tends to cause problems for people implementing it. So, while there are quality servers and clients for it -- be prepared for hard-to-fix problems along the way.
0MQ is a counter point to this: support for federated and flexible topologies and simple protocol. There is a NIF based Erlang binding for it, which is excellent.
