You know I just tried a code fragment and got the parent method to work 
with an instance .. so maybe you don't have to subclass. Here is a 
transcript illustrating the idea:

 >>> class DAD:
...   def methodx(self):
...     print "DAD-methodx"
...
 >>> class SON(DAD):
...   def methodx(self):
...     print "SON-methodx"
...
 >>>
 >>>
 >>> billy = SON()
 >>> billy.methodx()
SON-methodx
 >>> DAD.methodx(billy)
DAD-methodx
 >>>

So you can invoke the DAD.methodx via the billy instance of the object 
.. without subclassing. Now I wonder if this will actually work?
