pyro proxy method returns class instance

[John Hunter]

I am trying to use a pyro proxy instance to call a method that returns
an instance of a user defined class

    import Pyro.core
    from Pyro.errors import PyroError

    class SomeClass(Pyro.core.ObjBase):
        def __init__(self):
            Pyro.core.ObjBase.__init__(self)

        def speak(self):
            return  'hi'


    class MyProxy(Pyro.core.ObjBase):
        def __init__(self):
            Pyro.core.ObjBase.__init__(self)

        def get_some(self):
            return SomeClass()

    Pyro.core.initServer()
    daemon = Pyro.core.Daemon(host='localhost', port=2358)
    daemon.connect(MyProxy(), 'MyProxy')
    daemon.connect(SomeClass(), 'SomeClass')
    daemon.requestLoop()


And my client looks like

    import sys
    import Pyro.core

    Pyro.core.initClient()
    hostname = 'localhost'
    port = '2358'
    URI = 'PYROLOC://'+hostname+':'+port+'/MyProxy'

    a = Pyro.core.getProxyForURI(URI)
    o = a.get_some()
    print o.speak()


But the client call o = a.get_some() fails with 

  AttributeError: 'module' object has no attribute 'SomeClass'

Could someone give me advice or point me to an example that shows how
to do this?

Thanks.
