They state that there will be "code that activates automatically according to criteria you specify (e.g. SOPA returns)". I'd hope that includes the ability to activate only depending on the country of origin as well.
Sadly for me, American law has a large impact in Australia even though we're half a world away. The Australian government tend to justify a number of stupid laws and decisions with "but America's doing it and we're their friends". As such I'd personally elect to still trigger on American issues as they're still felt (although delayed) in Australia.
