I've posted this before: Harvard - H2O...and I'm still trying to wrap my head around potential uses. The concept focuses on "building an interlocking collection of communities based on the free creation and exchange of ideas."
Quote: "The recent development of the Internet has been overwhelmingly driven by commercial interests. Commercial websites must ultimately focus on making money. The founding premise of the H2O project is that the university world has something to add to the growth of the Internet that the commercial world cannot contribute. H2O aims to apply Internet technologies to the underlying aims of the academy -- the free creation and exchange of ideas and the communities formed around those ideas -- both within and beyond the confines of the traditional academy."
