Just on the biodiesel side of things, when you take a look at something for producing oil, the research that is going on right now is for things like algae, which would produce oil. Any of the other waste products are really a stream for cellulosic ethanol. So on the biodiesel side, what is likely to happen is that it will go from biodiesel to a hydro-treated product, which will still use oil; and then the research will come along in terms of perhaps other feedstocks on the biodiesel side.
You mentioned grains and oilseeds and the amount that is being used right now. It's a small amount of our total canola crop, obviously. Our focus is on premium markets. We're not a food crop that frequently goes into lower-priced markets. We're a premium product because of the healthy profile that we have, so we're always looking for opportunities for premium markets and for utilization at home, in addition to the exports we have.
