Easy to use distributed system?

[Jim Jones]

I am looking for a system in Python that will easily allow me to distribute 
processes across multiple systems?    So, if I have a function 'foo', I'd 
like to be able to call something along the lines of

distribute(foo(x))

And have the system figure out which node is available for process, and then 
have the results returned in some sort of callback fashion.

Any insight is greatly appreciated.
