…and voila: you get it! At least, if you are the entire faculty of the Harvard Law School or the School of Education at Stanford. I found this inspirational blog post by John Willinsky by following a post by Michael Nielsen on Friendfeed; it tells you more about the story at Harvard and at Stanford.
I see great potential in the idea that entire University-wide faculties would put pressure on journal publishers to allow the published papers to also appear in open-acess archives. My favorite sentence fragment from the blog post by Willinsky: “if you want Harvard authors in your journal, then these are the terms”.
