So far as I know, all the parts for the various songs are in the same style and key as the other parts for the same song. So yes, you could learn the parts independently then put them together in person or via skype (or even with a collaborative recording like some of members do with netGrass projects).
Great suggestion Shawn. I love the guitar break for Everlasting Arms as well. I never quite got it as fast/clean as I wanted (story of my life). I need to dust that off and go work on that one soon.
