Hi,
Nuxeo doesn't provide any direct integration with RabbitMQ.
However, the Nuxeo platform features an Event Service with can easily be plugged into RabbitMQ thru the mecanism of listeners. You can find a rough prototype here : https://github.com/nuxeo-sandbox/nuxeo-rabbitmq This sample shows how to propagate Nuxeo event into RabbitMQ.
On the other side it's quite easy to add a new service in Nuxeo that would subscribe to a RabbitMQ topic and propagate events from that topic into the native Event Service.
