This is, without a doubt, one of the most unique, RA programs I have seen in some time: Canisius College - Anthrozoology Online Master's Degree I think Wales-Lampeter has a similar program, but I have never seen such an offering in the U.S. It does require some residency over extended weekends, but seems tailored to distance students.
It sounds like a fascinating program. Too bad there isn't any relation to my current field(s) of study!
