Actually, we're looking at that right now, what's being done elsewhere, what the laws allow us to do, because the privacy laws in Canada are very strict.
We also have to be concerned about the different levels of airports in Canada. You can have a system for international airports, and others for regional airports. Regional airports can't necessarily afford to have the equipment that international airports have to have, so we're looking at all these elements.
Of course, international travel is a major concern. That's where a lot of the traffic flow goes. The big-city airports, part of the national airport system, could have a system in place, but I don't know if that's applicable to all the smaller regional airports. There are hundreds of regional airports in this country.
