If I subclass the Marshaller and Unmarshaller and

I needed to adapt the type mapping in xmlrpclib a
bit to better fit our needs. This is done by
adding a few more methods to the Marshaller
and Unmarshaller (it's a hack, but the module doesn't
allow any other method, AFAIK):
def install_xmlrpclib_addons(xmlrpclib):
m = xmlrpclib.Marshaller
m.dump_datetime = _dump_datetime
m.dispatch[DateTime.DateTimeType] = m.dump_datetime
m.dump_buffer = _dump_buffer
m.dispatch[types.BufferType] = m.dump_buffer
m.dump_int = _dump_int
m.dispatch[types.IntType] = m.dump_int
u = xmlrpclib.Unmarshaller
u.end_dateTime = _load_datetime
u.dispatch['dateTime.iso8601'] = u.end_dateTime
u.end_base64 = _load_buffer
u.dispatch['base64'] = u.end_base64
u.end_boolean = _load_boolean
u.dispatch['boolean'] = u.end_boolean

It would be nice to open up the module a little
more so that hacks like the one above are not necessary,
e.g. by making the used classes parameters to the
loads/dumps functions.
Then you'd run into the same problem, though, since now
subclasses would need to access the dump/load methods.
PS: Standard support for None would be nice to have
in xmlrpclib... at least for the Marshalling side, since
this is a very common problem with xmlrpc.
