You don't seem to be saying that government should be choosing the winners in terms of investing, at that stage, with dollars.
May I ask whether you think it's a difficulty for government to choose among the different technologies, or choose the winners, in the sense of saying that these are the ones we're going to partner with to try things in government? Would the list be endless? Obviously, it's much broader than lighting. There are some things that perhaps government couldn't be a guinea pig for, but in choosing to be a guinea pig, aren't there times when we have to kind of choose and say that we think this one is going to succeed and that one isn't?
