In our case, the back-end machines will be .net or possibly Java.  The front end web-UI will be python. (Likely TurboGears 2)

As it stands now, the front end machines will be calling specific functions on the back-end boxes via a basic HTTP/XML API.  For instance:  "Place order for customer X"

The back-end machines do whatever processing they need and reply with a result code.  (Success, No Stock Left, System Busy, etc.)

My idea was to use RabbitMQ for the request transport instread of HTTP.  Is this a resonaable idea? Can/Should RabbitMQ be used in this sort of environment?
