"As for the risk of a lawsuit from the Recording Industry Association of America, the selling point for new versions of peer-to-peer networks in recent months is that they can guard the identity of users. The most popular now is Earth Station 5, based in, of all places, the Jenin refugee camp on the West Bank. After the RIAA said it would sue, its software was downloaded more than 16m times in 90 hours. So far, it seems to work."
