The lawsuit is being sponsored and funded by the EFF. More details on the EFF's current cases can be found at http://www.eff.org/Legal/active_legal.html; they are a non-profit and will need donations now more than ever: the RIAA has much deeper pockets than the good guys in this case. I'm glad I made a donation just a few days ago; if you find yourself agreeing with what the EFF stands for, I hope you'll consider donating too---they accept credit cards and paypal and all sorts of groovy electronic means to make things easy.
OK, this is the end of this public service message. =)
