[python-win32] Passing an IDispatch pointer

[apocalypznow]

If a Python call to a COM server passes an IDispatch class (ie: 
pointer), could the COM server then potentially just call a method on 
that class?  The reason I ask is because there was a question about a 
COM server firing events such that the communication between the COM 
server and the Python client was asynchronous.  If the COM server could 
hold an IDispatch pointer to the Python client, and can call methods on 
that passed in class, then we have a solution for asynchronous calling 
don't we?
