Dan, going down this path puts you right smack in the middle of esentially creating a e-Learning solution for your course which may be more effort than you want to dedicate to this idea!

I would recommend merely going for the quickest ad-hoc solution right now: Upload your content to YouTube and you can then easily embed it's feed on your site and then "wrap" your e-curriculum around that (for example, by having an IM chat feature on your site, locking the feed until it's time for class, and providing a centralized number people can call....boom, instant classroom!!) .

Otherwise, as Nitro did an excellent job of explaining, you may be looking at more money and trouble than it's worth!
