While the idea is founded in solid ideas and overall good marketing, there is one factor being missed here, departmental textbook adoption. Colleges get a lot of "incentives" from publishers to use texts, often in the form of additional "resources", such as classroom aids and instructional equipment. In some cases, schools even get paid to select a certain book. The entire thing is very corrupt, and as a result, open source will not work. If you don’t believe me, take a look at online learning environments. Moodle is free and open source, Blackboard is thousands per semester. Every school in North Carolina uses Blackboard, if not primarily, then somewhere, but very few use Moodle or any other free platform.
