If by "on line" you can include all distance learning, or non-resident approaches, there are quite a few options. And if a really short residency (a few weeks, typically) is a possibility, there are many more. Edison State, Acadeia, Global U, Lakehead U, Oral Roberts, Stephens, U of Alaska, etc. As always, it pays to shop around for cost, academic model, and so forth.
