I'd like to provide a few thoughts on that. For me, the answer to both the questions you posed is really that there's a combination of factors, and right now we're coming to a point at which enough of them have come together that something has clicked. Kory talked about world energy prices; certainly that's a big pressure. In this country, you look regionally; we started in the prairies and realized this was something that could be very good for the farmers as well, so there's a component that's come together. If we put enough provinces together, all of a sudden folks like the petroleum retailers say that it's going to be really hard for them to make boutique fuels in all these different places, so why don't we standardize it? For me, that's another very big component to talking about this nationally: the fact that as soon as you get enough people on board, enough provinces on board, all of a sudden it makes sense to go to the full country, as opposed to letting it evolve one after another and having specialized jurisdictions.
If you put all those components together, something has clicked, and that's the reason we're talking about it today--multiple reasons.
