I think one of the things that David had talked about was that we could already capture CO2. We need a lot more deployment, so that we're talking about R and D on the large scale. So I think one of the places that we are talking about investment or incentive is on that large-scale deployment initiative, and that is putting a backbone out there to move that CO2 where you need it, and looking at how we can subsidize that or incent that. It may require at some point that the various levels of government just decide they're going to be an investor in that pipeline, and we'll look down the road to whether they can get a return on that direct investment as the CO2 gets used for enhanced oil and enhanced gas and coal-bed methane.
