It's such a grief that there is no ruby support yet. It would help a lot with our current project where we have site written in ruby/rails and backend services in python. We currently use Redis a broker between the two. At the same we've been looking at zeromq as a possible and simpler alternative.

Can developers share some info about their current roadmap? What languages will be supported next?

Check out JSON-RPC. Jimson is a good JSON-RPC client for Ruby. http://github.com/chriskite/jimson

We did python and node.js first because we use them a lot internally. There's no firm roadmap for future implementations, but we're hoping once the protocol is well-documented, implementations can start growing organically.

Note that a Redis transport is something we're considering. Also check out stack.io: http://github.com/dotcloud/stack.io

Would a redis transport replace zeromq and what would be the advantages?

No, it would be an additional option. ZeroMQ will always be supported - we use it enormously at dotCloud. Another transport we plan on supporting is websocket.

Each transport has its advantages. Zmq is incredibly efficient, very flexible and leaves you in full control of your network topology, but it requires a firewalled trusted network, and doesn't provide ready-to-use broker or naming facilities.

Redis can be used as a very efficient broker and discovery component, and can be more easily included in your web stack, but it limits your flexibility and becomes a potential spof.

The good news is, once zerorpc supports multiple transports you can stary with one and swap it out for another without changing your code.
