Integrating Another Message Queue with IIS Hosted Workflow Service

Currently, I am using MSMQ to queue messages for IIS hosted workflow services to handle. However, I would like to use another message queuing system in开发者_运维问答stead (eg - RabbitMQ).

I know RabbitMQ already has WCF bindings, but are there more components required for this to work with IIS hosted workflow services (perhaps some hook into WAS)? How would I go abouts switching from MSMQ to RabbitMQ, or another message queue product?
