Nice.

Or if you are really lazy, use this modification:

class Tee:
    def __init__ (self, *instances):
        self._instances = instances

    def __getattr__(self, name):

        def call(self, *args, **kw):
            for i in self._instances:
                getattr(i, name)(*args, **kw)

        setattr(self.__class__, name, call)
        return getattr(self, name)

It creates methods lazily on the fly as needed.
