That's a very sad requirement indeed.

It's also on the Pirate Bay.

Try this from a Linux machine. http://www.go-mono.com/moonlight/redirector.html

I got the following 403 Error, which is kind of amusing.

  Forbidden

I wish the audio didn't have noise artifacts ("clicks") from SilverLight's encoding that make it a bit annoying to listen to after a while, and that Microsoft had listened to it after encodeing or would have been so kind as to fix after it was brought to their attention years ago.

Hopefully it will work with moonlight but somehow I doubt it. It's most likely for silly DRM reasons :(

What better way to preserve such a valuable educational resource for the future generations than wrapping it into a failed proprietary content platform designed to keep people from using the content!
