I think they're early days. We are, as I mentioned, looking at various aspects of virtual currency and money services businesses and how those interact. Certainly, as a country and as a regulator, we have an obligation to look at emerging trends, and certainly there are a number of early lessons associated with a whole host of interactions with virtual currencies, and that's going to evolve.
New platforms, new mechanisms and new exchanges are going to take place. I think it is up to us to look at some of the best practices from other organizations, as well as ours, and to evolve as the technology evolves and as the world evolves.
