If I could respond, one of the things that's unique, I think, is some of the new technologies that are being attempted. I'll give you an example. In our part of the world, we have green-based technology. From my understanding from the engineers, a corn ethanol plant will just be able to handle corn. A wheat-based ethanol plant will be able to handle wheat and corn. We think that's a nice flexibility, from that perspective.
But there are some unique things going on, and I'll give you an example. In Nebraska, a company called Abengoa has partnered with a firm called SunOpta. They're doing a pilot plant, building a pre-treatment plant beside a grain-based plant, where they're attempting to take a cellulose product and converting it into ethanol within the same factory. So whether they're successful or not, time will only tell. But it's really unique, if you think that, going forward, this plant may be able to handle two streams of material. That really makes it quite dynamic. That's what's happening in research and development just in North America alone.
