I enjoyed what I read so far of the zeromq page.  I'll hope to come back to it later.  The oddest thing I saw so far was the consumer PULL effectively taking all available messages from a producer PUSH, as fas as I could tell, rather than being able to specify to only take "as much as you can chew right now" or something.  Maybe that's addressed later in the document.

Has the Rabbit-on-top-of-0MQ code been mentioned here?  I haven't seen it discussed, but I might have missed it.

https://github.com/rabbitmq/rmq-0mq/wiki/

The "Known limitations" discussed at the bottom of that page look serious, but it also looks like this is early days for the integration project.
