Just something like:

class foo:
    self.__init__(self, parent):
        self.parent=parent

class bar:
    self.__init__(self, parent):
        self.parent=parent
        self.foo=foo(self)


class myclass:
    self.__init__(self, parent):
        self.parent=parent
        self.bar=bar(self)

Now in foo I can reference things from myclass easily
self.parent.parent.  Or setattr(self.parent.parent, value).

Hope this helps.
