[Twisted-Python] Question about multiple XML-RPC handlers

>From the docs I see this example on how to implement a XML-RPC service :

from twisted.web import xmlrpc, server

class Example(xmlrpc.XMLRPC):
    """An example object to be published."""

    def xmlrpc_echo(self, x):
        """Return all passed args."""
        return x

    def xmlrpc_add(self, a, b):
        """Return sum of arguments."""
        return a + b

def main():
    from twisted.internet.app import Application
    app = Application("xmlrpc")
    r = Example()
    app.listenTCP(7080, server.Site(r))
    return app

application = main()

if __name__ == '__main__':

Test it with :

>>> import xmlrpclib
>>> s = xmlrpclib.Server('http://localhost:7080/')
>>> s.echo("lala")

All is well and fine. But I need to differentiate abit, more like :

>>> import xmlrpclib
>>> s = xmlrpclib.Server('http://localhost:7080/')
>>> s.Example.echo("lala")

For instance, if I create another XML-RPC-handler:

class Dummy(xmlrpc.XMLRPC):

    def xmlrpc_subtract(self, x, y):
        return x - y

I want someway to register it with the server and be able to call :

>>> import xmlrpclib
>>> s = xmlrpclib.Server('http://localhost:7080/')
>>> s.Example.echo("lala")
>>> s.Example.add(1,2)
>>> s.Dummy.subtract(1,2)

I've hacked the current XML-RPC code in Twisted abit to fit my needs, but
I'd like to be able to use the standard Twisted framework for this, not some
ad-hoc/mediocre/experimental thingy. Can I create a root-request which
somehow redirects the call to the correct instance/method if found or give a
proper failure-result if nothing is found?

Any clue or hint would be highly appreciated.

Best regards,
Thomas Weholt
