Creating COM server Events?

[Dan]

I have need to create a com server that will fire events back to
clients. I have looked at some of the documentation and I am new to
Python so cant quite get it. I have created an IDL file of the
interfaces. Can someone tell me approximately what needs to be done
here. I have seen examples of implementing the regular interfaces but
don't know what to do about the events interfaces.The vid...Events
interface is the main question here. In regular com development you
would implement something along the lines of Fire_OnNewData(). My Com
developement has mostly been with Borland tools and they do quite a bit
for you, As I hope Python will. Heres the IDL:

   interface IVideoVisitationPython: IDispatch
