I take your point.

Have you considered a layered approach to this problem?

For example:

Client                                                                  
Rabbit Server

----------------------------
| Command Line      |
----------------------------
|      CLI Parser          |
----------------------------						  ----------------------------
|  API Method            |						 |     API Invocation     |
----------------------------						  ----------------------------
| Hessian Encoding |    					 | Hessian Decoding |
----------------------------						  ----------------------------
|       AMQP                 | ----------wire--------------> |        
AMQP                 |
----------------------------						  ----------------------------

That way you wouldn't need to write any server-side parsing and  
response generation, and you can piggy back off an already existing  
mechanism.

All you would have to do is create the API definition in Python, but  
this is just copying the Erlang module interface definition to Python.  
All of the marshaling and unmarshaling is done for you.

HTH,
