I was accepted into this program, and I just went over the weekend to check it out. It's fantastic!
1) It's small (they accept 4 a year), so there's a real collaborative/communal feel to it. The students seem to really like each other.
2) The program is designed to be comparative in terms of the traditions you study. You major in one religious tradition and minor in another and work on comparing them to each other. Most people in the program are working on Islam and Christianity (which makes sense because of Georgetown's academic resources).
3) You can draw on other programs at Georgetown for your coursework, so there are a lot of courses you can take for credit in, say, Arabic and Islamic studies.
The program is pretty young (I believe it was founded in 2005), but it's Georgetown!
After visiting, I was more than convinced, and I'll be starting there in the fall.
