I agree it would be very useful to have full COM support in Emacs on
windows. My solution is to use Pymacs which allows you to use Python
to script emacs. Since Python has excellent COM capabilities this
makes simple use of COM very simple. The only problem is that Pymacs
is that communication has to initiated on the Emacs side. This means
that anynchrounous notifications (COM events) might be difficult to

As I think about it COM events need not be that difficult, you only
have to set up some polling scheme that calls pymacs regularely,
pymacs then polls the COM subsystem nonblocking for events and if
present does what it needs to.

If want a more transparent way of initiating calls from Python into
Emacs I suggest you contact Francois Pinard who is the maintainer for Pymacs.
