Shippy writes "Palisade Systems is about to launch new software that can identify and block copyrighted songs as they are being traded online. However, the article fails to mention that it will also stop legal song downloads. The software blocks anything that's copyrighted, whether you already own the song in another format or not. Here's some snippets from the article: 'If installed in a university, for example, it could look inside students' emails, instant messages and peer-to-peer transfers...', and 'Jacobson said the identification process would not work on an encrypted network, such as is used in several newer file-swapping programs. However, the Palisade software could also act to block those applications from using the network altogether.' Great."
