Daniel Reetz is the mastermind behind http://www.diybookscanner.org/ . It is an incredible community building open source software and hardware for book scanning using affordable consumer equipment. The project has evolved incredibly over the last few years and now include beautifully hackerspace-made scanner kits. He seems like a great speaker and I believe his perspective would be different from the traditional academic/research library focus.
