Hi. I'm not an html buff at all, but I have been requested to help in finding an apporipriate web host/website creator that would be good for a teacher looking to offer different study methods to her students. Here's what I'm looking for:

+Password protected membership
+pay for membership
+they want to be able to have their Powerpoint slidehows in a viewable format ON the website (not available for download, but kind of like a flash video embedded in) that would only be available for those paying for membership. I understand doing this with a powerpoint file may be a little farfetched or impossible when it comes to website creation made easy, but is there some alternative that could offer the same security of the content not being freely distributable while still not requiring expensive Flash creation tools?

This is pretty much it when it comes to the standards that must be met. If you could help me, I'd be grateful. Thankyou!
