1. There are ways for a manager of a P2P network to monitor the type of files that are being shared. The fact that there is news of people who share copyrighted material on P2P being caught and penalized indicates that this is possible.
Two ways the manager of a P2P network can monitor the types of files that are being shared is through a software or website with tracker listed. The file is registered with a server, called tracker, and the tracker keeps track of which seeds and peers are in the network. The seeds are clients with completed files, and the peers are clients with incomplete files. P2P peers can connect and download segments of the files from any seeds and peers from the tracker.
If the P2P network is using a trackless system, (decentralized tracking) every peer acts as a tracker through the distributed hash table (DHT) method. The manager can also monitor the network by the ping monitor method. A ping command is sent to every peer machine within the network using a peer protocol on the peer machine, and it will request a response with DHT info. If a response is received at the sending peer machine, the responding peer machine is operating, and the monitor program will receive the DHT info from each peer machine.
2. I think it is worth tracking because it could help protect copyrights.
3. I believe the monitoring should be paid for by the tracker website and the P2P software provider because they are providing the P2P service and should be liable for tracking any illegal downloads that are occurring on the network.
