Passing this bill will make things worse for entities trying to fight online piracy, because, more people who want to access blocked sites will learn about and use VPN's. This will create business for the foreign ISP's running the VPN's, and it will render ALL traffic between computers and foreign ISP's via VPN totally encrypted and untraceable, save for raiding the foreign ISP (and they might only have access to logs that the ISP maintains; most VPN services don't keep logs). As it stands now, they can at least send cease-and-desist warnings to US based IP addresses. They won't even be able to do that if you have a nationwide block. That means everyone in the country can still access the blocked site by using a VPN, and they won't be able to track it, save for a bunch of IP addresses on a public tracker (or whatever) pointing to various foreign ISP addresses that they won't be able to do anything about. I guess they can block the entire foreign ISP, but that would open up a whole new can or worms and will cause a whole host of other problems. What it basically boils down to is, blocking specific sites via ISP's by forcing them to block them by making it a law is NOT going to stop piracy, and will make it HARDER for companies to fight it than it already is. They are cutting off their nose to spite their face.
