Although an international instrument is not for tomorrow—I'll be more optimistic now—there are certainly discussions among countries on how to make privacy laws more congruent—not completely consistent but more congruent. Offices like mine co-operate for the enforcement of these privacy laws, to ensure that they result in similar outcomes. So we may not reach an international set of rules soon, but I see movement towards more consistency.
