Might I recommend circuits (1) as a general purpose
framework that you can build your application on top of.

circuits will allow you to communicate with long-running
background processes, communicate between processes
(by way of a Bridge). All communication in circuits is
asyncroneous. circuits has also recently seen the integration
of the multiprocessing package from python 2.6/3.0 so you
can create processes and have inter-process communication
seamlessly. In fact, parts of your system can even run on other
nodes (you mentioned clustering).

Feel free to talk to me more about this in detail...
