Mike,

I will read and respond to your mail in more detail later, but here  
is an easy part to answer:

You are correct.  In Python, any object with a __call__ method  
defined is callable in exactly the same way as a function.

 >>> class Foo:
...  def __call__(self, x): return 'foo %s' % x
...
 >>> f = Foo()
 >>> f("bar")
'foo bar'
