LimeWire late Tuesday said that it had secretly installed a 'cut-off' switch in its peer-to-peer client to accompany the court-mandated withdrawal of its app. After a rumor from PCMag, company representative Tiffany Guarnaccia acknowledged to CNET that a summer update had given LimeWire the ability to isolate clients from the Gnutella network, rendering the app useless. It had also changed its update policy to both patch automatically and to refuse to open if a user wasn't running the latest version.
