Napster here is the software to monitor users.

The site 7amnews.com New Zealand has published pictures of the Media Tracker, the terrible software developed by the International Federation of the Phonographic Industry (IFPI). Media Tracker detects a playlist, the network that are shared (Napster, Freenet, Gnutella), the IP address of the person who puts incondivisione, and the name of its host or ISP, as well as date and time when the File sharing has begun. Everything is stored in a database that obviously allows to cross the information and then detecting statistics (for example) the Service Provider most active in these operations. Another option included in the program is to immediately send an email deterrent users identified.
