I missed this part of your reply in my first read.   Note that you can do 
this with an interface like:

    class IFoo(Interface):
        def get_thing():
            """get the thing"""

    class Simple(Adapter):
        protocols.advise(instancesProvide=[IFoo],asAdapterForTypes=[...])
        def get_thing(self):
            return self.subject

And just have the code call "IFoo(ob).get_thing()" instead of just "IFoo(ob)".
