As far as I understand the problem is at the server side
if you receive a xmlrpc request and not if you use a 
XMLRPC client and will send a request.

The z3c.jsonrpc doesn't use anything similar then the xmlrpclib 
implementation. I mean the jsonrpc and xmlrpc implemenation are 
not comparable for that problem.

The z3c.json package offers a JSON python client. Only this
client uses similar patterns then the xmlrpclib package.
