I don't know much about Power Point but you might look at is Google Docs
http://docs.google.com/ You can upload a Power Point file and save it as one of thier presentation files and generate code to embed it in a page. One reason I am looking at Google docs is that it might be a cool way to offload some bandwidth -since Google hosts the docs- or even to mirror some content. I created a quickie sample using the Google Docs site and posted it here to see how easy it was
