Judaism without borders?

I have just received an email drawing my attention to the site Judaism without borders. It's an interesting name I must say. I have only just heard of it so I am not vouching for it. I am simply drawing attention to it so others can assess it for themselves. This is what they say about themselves:

Our mission, as American Jews committed to full awareness of the Israeli-Palestinian conflict, is to build trust and goodwill between Jews and Palestinians through direct encounter and direct service.

They are organising a tour of Palestine and they have a blog called the Peace Yeshiva.
