The technology we're expecting to use in the driveway is not DNA. It's wavelength technology. That is hoped to be a much simpler methodology.
I have to say, I'm not really competent to go into the technical aspects of that at this point. I can certainly go into that afterwards and get someone to provide some information if you want. At this stage, technologies are being developed that are also DNA technologies, but that's for a different purpose. The driveway technology would be one that we expect would be a relatively quick look at a sample in terms of wavelength technology. However, at this stage I think it's mainly a question of making sure we can identify all varieties and that we can make it quick and low cost. We're not quite at that stage yet.
