I'll speak to that first. As we talked about with part IIIs, I can see some value in perhaps having a pilot department, or two or three. However, I don't want to bring you a mixed set of estimates--a bunch of departments on one system and a bunch of departments on the other. That won't serve you, and it will be a lot harder for us.
I mean, certainly if we're going to do this, we need to do it in a measured way, but measured in few years, not decades.
