I wasn't there, so I can't speak to the overall crowd dynamic, but other than one guy who took issue with the whole concept of tolerating non-Christian beliefs, it seems to have gone quite well. This type of dialogue is very encouraging on many levels. I must confess I was not aware of this much religious diversity in my hometown.
I don't pretend to know as much about theology as Dem Bones, but I've always gotten the impression there is more common ground than division between what these three faiths basically believe--monotheism, shared prophets such as Abraham, and the like. I think most religious violence stems from a lack of understanding, and it would do us a great service to learn more about those who see things differently.
