That's really interesting, actually. As you're talking about nanotechnology, I'm thinking about the Edmonton Research Park. Mr. McDougall is very familiar with some of the work that's going on there at the University of Alberta and other places where we've seen that very technology.
This is the last question, though. I'll come back to you folks. You talk about retailers. It's really interesting, because I think about knock-offs being sold in a back alley somewhere or something else. You're talking about big-name retailers who are being fooled by this stuff.
Maybe you could speak to how that can happen and to what extent that is happening.
