I guess I will have to switch to PB from XML-RPC. XML-RPC was convenient 
since I could write client apps in just about any language and access 
the system.

I know it is difficult in passing things between Python and anything 
else. Do you have any words of wisdom on how to limit the problems so 
that non-Python apps could talk to a PB enabled server?
