LimeWire developers are working of code modifications that will prevent users of future versions of the popular P2P client from sharing copyrighted works. Future versions of the software may check to see if material presented for sharing is copyrighted before blocking sharing if no suitable license can be found, Slyck reports. Users would still have the ability to trade their own work or files they have permission to distribute via a Collective Commons license.
Since LimeWire is working on the Gnutella network, there are plenty of other Gnutella clients to choose from if you find this feature annoying.
