I realize this is an old post, but I have been on a similar quest so wanted to reply! The only online Master's in Sociology programs I've found are through Arizona State University and New Mexico State University. Both are non-thesis programs. ASU does give you the option of writing a paper for your capstone thought. The University of Alabama-Birmingham also has an online Master's in Applied Sociology. From what I've been able to find, there are slim pickings for online/distance degrees in Sociology.
