Hi John I was looking at using Stomp and ActiveMQ in a future project to integrate with my Java based services, so I find it interesting that you are having implementation issues. ZeroMQ does look good and is a great alternative, have you considered using their protocol binding http://rfc.zeromq.org/spec:13. I see that the Javascript and I think Node.js version make use of this. check http://www.zeromq.org/bindings:_start
Good luck and it would be great if you could report on specific issues with Stomp and ActiveMQ. I'd love to use an 'enterprise' communication layer and bind to Javaspaces, JBossCache, Apache Camel or other useful integration frameworks.

I have a system with multiple servers, some in Java, some in Clojure, and the Console servers developed in Seaside running on Pharo. I need to have all these servers talk to each other, and today I'm using JMS over ActiveMQ to do that. I need to use Stomp as a protocol to allow my Console servers to push data updates to the main servers, and its fragile. It could be that my implementation is wrong, and you could advise on that. What is your experience in pushing messages from Smalltalk VMs to Java and C servers? Any help would be most appreciated. (My systems supports 200 end to end transactions per seconds, with many thousand concurrent transactions. It's deployed on 16 servers in an EC2 cloud) Why would ZeroMq be better? I have 20 year experience writing network servers, and to honest, I'm not even sure where to start with an answer to that question. Again, if you could help me out here, it would be most appreciated. Perhaps, your experience in developing large scale network applications, would be insightful here.
