It gets harder if it's international, but they're working on that.
So is the RICAA... or however that anagram goes. The people trying to prosecute KaZaA, WinMX, Napster, and twelve year old girls. They're all working on the same thing... trying to prosecute local laws internationally.
Of course, we could always hack thier servers and crash them.. .oh, wait, they already tried that with KaZaA and Morpheous.
