I've used zmq (or is it 0mq) in the past. My complaint with 0mq is that you wind up needing some sort of service discovery service from what I can tell. In order to get everything working, each client needs to know about at least one servant. Ideally, each client needs to about all servants and use a load balancing algorithm across them. I'd need to keep this configuration at all clients synchronized. I'm aware there are tools to do this, but ultimately I am not the person in charge of operating this.
