I just want to make one clarification, because it's been picked up on a couple of times. I didn't mean to say that pilot projects in and of themselves aren't useful, but the point I wanted to make is that pilot projects can't be the ends unto themselves. We need to be thinking beyond pilot projects and how we implement these things on a large scale. So that was the point I was trying to make, not that we don't need some pilot projects in a handful of areas, but that we need to be thinking much bigger than that and in much larger penetrations than pilot projects.
