Interesting thought. SUNY/ESC (I don't think we are not yet quite officially the Open University of New York but Betty might know more) is starting a Master of Arts in Adult Learning in January. It will probably have courses in OER and its uses...especially since I am going to ask for permission to develop some.
(My actual "terminal degree" is in adult education. We also have a new masters in technology and learning and one in the proposal phase in community and economic development. I am not sure we will ever have one strictly in OER etc. but with us one never knows.
