"So far, the music industry has yet to challenge bigger players with deeper pockets like AT&T, Comcast or Verizon, though these giants are likely watching the case with great interest for liability reasons."

In a better world those larger ISPs would pony up, band together and help out the little guys, in their own enlightened self-interest, a la Newegg.

But they probably see it in their thuggish self-interest to let the little guys be sued out of existence, and take over those customers. And then they may start fighting this.
