Well, yes. If we can't rely on regulation—and I've spoken about this recently—and the regulatory regimes that exist today to preserve competition, the next step is not to give up and say, “I guess regulation doesn't work to preserve competition.” The next step is to move towards what you're referring to, I believe, which is structural separation, where there is a separation of the operations divisions and the retail arms of the large incumbent carriers. We've seen this in other parts of the world as well.
I think that Geoff White, my associate, has something to say on the matter as well.
