Why? It's worked great for me. I'd like to know what limitations you've 
encountered, apart from execution speed.

Something more scalable, mature and OO than either of those is CORBA. 
There are CORBA implementations with Python support, and with Java support.

For Python support, go to: http://sourceforge.net/projects/fnorb, or 
http://omniorb.com

For Java: http://jacorb.org is one option, but I believe there is built 
in CORBA support for Java these days.

CORBA has the additional advantage that it is location transparent i.e. 
you can trivially move your objects to separate hosts without changing 
your code.

Apart from that, I don't think there's much else. The processes are 
going to have to communicate *somehow*.

Derek.
