From my perspective, it would be to be able to participate in the auction upfront, but also a horizon perhaps two years afterwards, where if the spectrum is not being used the licensee could be required to give it back, and by requiring to give it back they would also be incented to subordinate it before they had to return it. It could be an effective way to ensure that the spectrum, the scarce commodity that's out there, is being used in the rural areas.
