Python and COM?

Thanks for the info everyone.

I think that my first generation I might just release with some docs and examples.  Then work on the IDL.  I signed up on the pycom-dev list... I'd love to see this happen.  It's so much nicer in Python that C++ or VB for creating objects.  If anyone knows how far along Christian Tismer is with what he was working on, or what's left to be done, I'd like to help if I could.  I just don't know if I'm ready to play with the big dogs yet ;-)

P.S.
Start a big drive tomorrow. I'm moving back to Denver, CO, from AL, so I will be gone for a couple of weeks (switching providers, looking for broadband, etc...).  E-mail to my geocities address will still reach me when we get there.

Bye.
