Okay, yes, I think they're going to have to buy the products. Again just kind of going back to this call I had with the folks, there is a real demand, I would say, from the people that have the product, that need the product, that actually are using the product. The issue has been, like with a lot of companies, the clamps have been put on the capital budgets at the top. Obviously, we make the same kind of decisions here at ESCO with Gary and I. We are a lot more strict about what we approve and what we don't approve on the capital side. But certainly I would say that the demand is going to continue to kind of build up because there is a requirement to do this testing; they can't just ignore it. And that's a reason I'd say that our service business has really held up well. I think that's probably going to accelerate some as we start looking into the out years because, to the extent that they don't do some of this, some of the capital buys, then they are going to have to find another way to do it because the requirements are still there. So, fortunately, we can kind of play both sides of it, if you will. We can provide the services or we can provide the hardware. But I do think that particularly with Doble, what happens if they don't do this type of testing and honestly increase this type of testing, that the consequences are pretty dire. So I think they're going to do this one way or the other and I think we are well positioned to do it for them in a couple of different ways. As far as the international things, they are going well. There's not a lot to report there other than we continue to have good success with our pilots, lot of interest really throughout South America, primarily in Brazil and Colombia as we've talked about before, and you've got a good team there. The other thing is what we're continuing to see in Asia, they are really moving forward to deploy a lot of smart meters. As I've talked about in the past, we've got two really solid partners there and we are working through how best to address that market with those folks and on our own as well. So there's a lot of good things going on internationally. As I said in my opening remarks, the whole issue there is always timing. But the international market always appears to move a little slower than we hope it does, but the demand is certainly there. And I think, over time, it's going to come to fruition for us.
