I think that Bard College in upstate New York offers a low-residency program, and I believe that Goddard College in Vermont also does. MFA programs are going through a bit of turmoil these days, especially with regards to offering traditional wet-darkroom/alternative process facilities and learning opportunities. If you approach an MFA program and say that you are looking for an MFA with the goal of enabling you to teach, you'll have a very hard time getting in. It's one of those odd hypocracies of the business - you have to have the MFA to teach, but to get the MFA you can't say that you want to teach. You're supposed to talk about how you want to take the two years (give or take) to really hone artistic ideas to a razor focus. Think of it as an extended artist-in-residency program with intensive guidance.
