Our use case for ZMQ_IDENTITY is this: We have a few stateful backend services that need to communicate with other servers. We need to direct requests to specific services, so round-robin balancing doesn't work. (We can't easily make those services stateless.) We use router sockets for that. I'm not sure that there's an easy way to do that without ZMQ_IDENTITY. Whenever we need messages to go to a specific machine, round-robin load balancing doesn't do what we need. In an ideal world, everything would be stateless, but sometimes we really do need to be able to address specific nodes. That said, if there's a way to do this without ZMQ_IDENTITY, I'd love to hear about it. Marcus
