Thank you, I will try that. Right now I've been trying to use win32com
for the server creation, but I haven't been successful yet (have not
explored it that much yet though). 

I have registered a COM server (it should only implement two methods,
"onMsg()" and "onNotify()", which should print whatever is sent to
them directly to stdout), but I need to create an interface which is
not an IDispatch interface and pass it on to the proprietary COM
server. This connection is needed so that the proprietary COM server
knows where to send the log and control data. 

Registering the COM object in the registry works fine, but how do I
make it look like a custom interface from the proprietary COM servers
point of view? Oh well, I will look at it some more tomorrow and
hopefully come up with a solution...
