If you go to limewire.com you’ll read:
THIS IS AN OFFICIAL NOTICE THAT LIMEWIRE IS UNDER A COURT-ORDERED INJUNCTION TO STOP DISTRIBUTING AND SUPPORTING ITS FILE-SHARING SOFTWARE. DOWNLOADING OR SHARING COPYRIGHTED CONTENT WITHOUT AUTHORIZATION IS ILLEGAL.
In the US, a court ordered Limewire to be shut down immediately. According to Digital Music News, the judge demanded that parent group Lime Group disable “the searching, downloading, uploading, file trading and/or file distribution functionality, and/or all functionality” of Limewire’s P2P file-sharing software. The news come from sources close to the proceedings, and official court papers are expected to be signed and filed as soon as today.
The problem is, that shutting down an already-distributed client is close to impossible. Limewire runs on the Gnutella network, a totally decentralized system which does not fall under the company’s control. The Limewire Store will continue, as will ongoing plans to create a legal, cloud-based music service.
