You do realize that a dam is a source of clean energy, right? Ever heard of hydro-electric power? Turbines?

That is what they're already doing. I work for one of the top 10 universities targeted by the RIAA, and the "offer" they make the students has absolutely no legal authority to it. They're quite literally "promising not to sue" if the student pays them some number of thousands of dollars. There is no suit being filed, no legal action being taken, no trial. Just a letter, an offer, and instructions to visit their handy website to make paying as easy as possible: www.p2plawsuits.com
