As you may know, I'm somewhat interested in the business of providing educational materials on the World Wide Web. I recall reading, some time ago, that the Massachusetts Institute of Technology (MIT) was releasing some of its course materials into the wild (AKA the WWW). Well, without much fanfare, they've opened the floodgates, and there's a lot more to come: MIT for free, virtually | CNET News.com

Happy learning!
