Carnegie Mellon is where I started my convoluted journey through the land of higher education. So, aside from my general interest in the RIAA's egregious misinterpretation of copyright law, I plan on following this story very closely. Good luck, kids.
There's a potential angle here that I don't think has been tried yet: equal protection under the law. What the RIAA is doing amounts to selective prosecution (i.e., only suing certain people, hoping to make an example of them). This is inherently unconstitutional.
Then again, who pays attention to the Constitution these days?
