It's a dumb idea - flawed with millions of different problems and basically lends itself to favouring countries whose majority of national assets are heavily based on intellectual property [hence the reason ACTA was put forward by Japan and USA - the later mainly due to political lobbying]
The reality is - enforcing copyright laws based on one jurisdiction [ala USA] - on every other jurisdiction is a bad idea. Of course, the USA tries to "force" its bilateral and multilateral trade relations with new clauses requiring higher intellectual property standards. This 'stark picture' is already being painted on the 2010 USTR Special Report 301 [basically bad IP enforcement countries - primarily the BRIC [brazil/russia/india/china] block] where not one single African nation is listed on the reports Watch List - WTF ? Yes, why are some of the poorest african nations strongly enforcing IP rights ? You guessed it - trade preferences with the USA.
So yes - it sucks "only within the United States" - but I would rather that than some moron in a USA movie studio office, sipping cognac and lighting up a cigar telling me how my country should run its domestic law [pardon the gross generalization of movie studio executives painted from movie studio produced movies].
No thanks.
