Cheers, that's helpful information.
I also read about that program (although, as I understand it, you only have access to the college at which you act as liaison).
I would also agree about the divide being as big as you want it to be, but there is something to be said about the university placing unnecessary hurdles in the path of the two groups interacting.
Princeton has the disadvantage of having a much smaller graduate population in comparison to Yale, so it isn't necessarily a clear-cut issue.
After my visits, I'll probably end up flipping a coin!
