I have been trying to achieve a similar thing as we speak.

So far I have decided the following:

1. You can recreate the online broadcasing stuff by using Windows Media Tools (www.microsoft.com/windows/windowsmedia/). Use these tools to record your video/audio if you want. There are numerous utilities here to create asf files.  Basically, at its simplest create a number of html files as your slides (these can be straight html or jpg/gif exports from PowerPoint). Using one of the Windows Media Tools (such as OnDemand Producer) add "commands" at the points where you wish to have a frame transition - a "URL" command with the page address as the parameter. Use http://www.domain/pahe.html&&framename as the syntax for putting the page in a frame.

2. Powerpoint 2000 uses a technology called VML (Vector Markup Languag). I do not know too much about this at the moment but suffice to say it is IE5+ dependant and I think a Microsoft technology. (This VML gives the scalable effect when you resize the window on a PP2000 web presentation).

3. PowerPoint 2000 uses some non standard trickery to update the frames, not the URL Flipping (thats its name) that I described in point 1. I do not know how to edit PP2000 broadcasts. To use the URL Flipping which will be the proper way of doing it from now, you need Media Player 7 beta or later. (This is all new stuff really).

4. I hope this all helps. There is a SDK for creating and editing asf files also available from the Windows Media download pages. This includes C++ code and documentation for development.
