The simple answer is yes, but it's not just us; it's the consortium we work with. In the development of that technology, or at least the deployment road map on natural gas, there was a component of detailed business modelling done to assess, analyze, and rank potential end-use vehicle applications. It was a full life cycle of the end users' needs associated with everything you've talked about. What is the infrastructure cost? What's the maintenance? What highly qualified people are necessary to be able to do the repairs, etc.?
As we go into implementation—and we are starting into it—we're using the same full-spectrum consortium, so that when we have an example of a trucking firm that has chosen to shift to natural gas, we can get real-time value information associated with that company and actually apply it then in a more generic way.
