Sending mapped instances over XMLRPC is basically nonsense. XMLRPC is
designed for transporting elementary datatypes over the wire in order to
invoke a remote method. It is not designed for sending instances of some
class and not for sending Python pickles. No idea what you are trying to
accomplish. Consider converting a mapped instance to dict and sending
this dict serialized in JSON format to a remote XMLRPC server.
