You need to have a look at win32com.client.DispatchWithEvents.  Python takes
a different approach to hookup events.

>>> import win32com.client
>>> help(win32com.client.DispatchWithEvents)

Not from an external process, no - xpcom does not work across processes.  If
you wanted to write a Mozilla extension (ie, some "chrome"), then other work
I am doing with the Mozilla guys will soon make this possible - you will be
able to use Python whereever you can currently use JS - but that's a
different story <wink>
