This seems to be fraught with peril - in fact your example
demostrates exactly why :^) While I assume it would be easy
enough to write an extension module with a C method that 
takes an id and makes a PyObject pointer out of it and returns
it to Python, the example above demonstrates why this would
be dangerous. After you set myObject=None, your myID is now
meaningless, and you'd get a wild pointer back from the
FindObjectFromId method.

Just my 0.02...
