Perhaps one other question would be.... You gave some good examples of where agri-products are involved in a final product that we might not normally assume, like in foam seats, etc. If the government were involved in this key step of moving something from the research lab to the market, how would one differentiate between all the different types of products and what actually has agri-content and what has less agri-content? Where would we start drawing lines to say something is worthy of effort because of its agricultural content, but another thing has less and something else has none? What's the model for that?
