MIT isn't the only one offering their courses to the masses for free. Many institutions, both K12 and higher ed, have their courses online now. Of those, many have the Creative Commons licenses that can allow for remixing the content. http://www.oercommons.org/oer/oer-providers has everything from Free High School Science Texts from South Africa to webcasts from UC Berkeley to MIT's OpenCourseWare, as well as dozens of other sources.
