[mod_python] persistent, reliable globals

Have you look at pyro (http://pyro.sf.net).

It's not a middleware, but will allow you to "play"
with Python object throught the newtork.

Pyro has caching mechanism.

As mention earlier, xml-rpc is a possibility too. no?

Those tool combine with mod_python is a powerfull
framework, no ?
