Ok, I tried to implement the fireEvent in what I have, but I keep 
getting an exception that says::

   TypeError: function takes at most 3 arguments (9 given)

For sink.Invoke().  It obviously takes 9 parameters, but I can't seem to 
convince the system of that.  ;)  Any thoughts? ::

         def fireEvent(*args):
             for sink in self._iterConnectionPointSinks():
                 params = DISPPARAMS()
                 params.cArgs = len(args)
                 rgvarg = params.rgvarg = (VARIANT * len(args))()
                 for i, a in enumerate(args):
                     rgvarg[i].value = a

                 Invoke = dict(sink._methods_)['Invoke']
                 Invoke(
                     sink, dispid,
                     byref(GUID()), 0, # lcid
                     DISPATCH_METHOD, # wFlags
                     byref(params),
                     None, # pVarResult
                     None, # pExcepInfo
                     None) # puArgError


The patch of my attempt is attached.

Thanks,
