Napster, maker of the popular MP3-trading software of the same name, has been working with Indiana University to reduce the amount of Internet resources being consumed by students using Napster. A ban on Napster will be lifted on a trial basis beginning Saturday, the school said in a press release. The jointly created technology instructs Napster to search for MP3 music files first within the school's computer network, then at other colleges with high-speed Internet connections. Only if the file is not found through these routes will the program go out onto the general public Internet, which transfers information more slowly. Since its debut last year, Napster has become a grassroots phenomenon, allowing MP3 users to quickly and easily trade files. In December, the Recording Industry Association of America sued the company, saying the program contributes to online piracy.
