I'm in a rush today but just wanted to draw your attention to this, which at first glance looks like a possible step in the right direction to getting a resolution to the file sharing issue.
A couple of MIT students have come up with a new system which taps into the MIT campus licensed cable TV network. The files are analogue not digital, which means the sound quality resides somewhere between a radio broadcast and a CD.
It means that the students get access to a big library of music and the copyright holders get paid a license fee. Sounds a better for the RIAA than a bunch of expensive lawsuits and PR disasters about suing 12 year olds and grannies.
