Well, the problem there is a lack of available $QUALITY courseware content as there are tools to do this sort of thing (Moodle, XO Server) and free content (moodle.net, Khan Academy, scorm modules) available in small quantities for some topics and languages. I would advance the theory that the art and science of developing useful and effective courseware is new and we (humans) haven't at all figured out how to do it yet. Various people I know are exploring this from different directions with their projects, EG: * AST is running with the free BBST courses * while the original authors of that free content have built a company around expanding and maintaining the curriculum commercially. * a friend is putting together work for hire 1000x level class material as part of her instructor position The economics of motivating class creation, much less improving $QUALITY or availability under free culture licences are ... well quick the thorny thicket.
