I don't think that would help. They can nail you for sharing files, even if the people you are sharing with are outside the USA. I don't believe law enforcement has to prove the other party downloaded anything, just that you were sharing.
What if someone in Germany was sharing a popular MP3. I download it in the USA. Does that make it less of a crime than if I downloaded it from someone sharing in the USA.
But to the point. These laws are stupid. File sharing is no different than what many people did in the 80's when they made tapes of music and shared it. Or taped music off the radio. I remember when radio stations used to not speak when a song started, so you could make a good copy. Now, the RIAA is going nuts and calling it theft. I always believed theft is those guys who profit selling pirated copies. But giving it away for free because you liked a song is not the same thing. Too bad the law disagrees with me. It makes me believe the RIAA used lots of cash to buy legislators to vote their way, after all, running an election is expensive.
If you ask me, the RIAA is a bunch of jackholes. Long before they started suing, they invaded the p2p networks and made available bad copies of mp3's. People would download them, and then realize it was 3 minutes of a screeching sound. I stopped buying music around that time and I remind myself just how friendly those big music companies are. I guess it wasn't good enough when I used to buy CD's and listen to the occasional MP3 on-line. Now they can live without my money.
And look at the trends with television viewing. Everything is going digital, so you won't be able to make a copy of anything. No more VHS, even TiVo is having a new flag which will force anything recorded to be deleted in 7 days (if the station uses the flag). And to top it off, when you want to fast forward commercials, guess what TiVo does? A pop up box with an advertisment is shows. Geez, isn't that why I'm fast forwarding. Lets face it, we live in a world where movie theaters force us to watch 30 minutes of commercials before they start the movie we payed $10 to see with the $6 popcorn and $6 soda. And when the DVD comes out, we are forced to watch previews of the FBI warning screen without the ability to fastforward. And a year later, the same DVD is released with special features.
They exists to rip us off. If they just wanted sales, they would treat the customer with respect. But there are too many people, and there is always someone willing to buy.
