I've seen several DL Master of Fine Arts programs, but not one that is 100% online/distance, until now. Bay Path University is a traditionally women's college in Massachusetts that offers its graduate programs to men & women, including the M.F.A. in Creative Nonfiction; Creative Nonfiction (MFA) Bay Path University | Bay Path University
There are 2 others, IIRC. National and some school in Texas (maybe TAMU?) http://www.degreeinfo.com/general-distance-learning-discussions/28319-creative-writing-dl-low-res.html
