I can safely say that I am totally titillated.
I'm chomping at the bit to see how closely what I've been considering as a strategy comes to what you describe.
Unless there's some SP lottery that I can somehow win without entering it, it'll be at least a year before I'd have enough to even consider powering down. I'm also under the impression that limited Power Downs might be a possibility in the future, as opposed to cashing out entirely over a 13 week period.
