Thanks for your answer.


I'll look at web2py.

However web2py seems to address the xmlrpc server (at least in your
example). The xmlrpc server application exists alerady and requires a
client certificate.

The client example doesn't seem to be using a certificate.

So I'll be reading a little into web2py.
