I hope all ISPs do this at once. I mean, hey, the US will be all over it and we all know there's no such thing as "Europe", "Asia" or "Australia". It would be a perfect opportunity to start up a small corporation that offers a "Freedom Flatrate" for way-above-fucking-competition fees that ignores this system. Profit + looking like the good guy!
