The reality is that the borders are a lot more porous than the borders we have here, and people do cross borders all the time.
I know when we work, for instance, in Benin, and we offer services to people from Benin, there are lineups of people who come from Togo. They cross the border and come to get free medication, free dental care, or whatever we have to offer. That's the kind of porousness that's going to happen. And it happens already today. One country may have a procurement process in place, and even though the drugs technically are destined to the people of that country, there are people who filter through that and get medication, for instance, in Kenya and get back into Uganda, where there's a shortage of supply.
