[python-win32] Passing an IDispatch pointer

Yep - you will probably need to call win32com.client.Dispatch() with the
object to wrap it into a friendly object though.

That depends on where you are calling from and on the COM threading
apartment you are calling from, but yes, COM does allow asynchronous
behaviour (via connection-point based events or otherwise)
