I agree completely with "omalleyj" ... we had a session with WPI at the end of the summer for several programming mentors from different teams in our area, and I think the general consensus was that this was great for rookie teams and teams without strong programming mentors - but it didn't seem that much different from what we were already doing (e.g., we already had 'subsystems' with well defined interfaces - we just weren't calling them that). But, as with all software - there are lots of ways to do the same thing, and you should go with what works for you.
