Well, P2P traffic has the tendency to use up every bit of bandwidth available. Since there's no way to detect encrypted P2P traffic without breaking end to end encryption, and NUS does not limit the bandwidth of each user, network saturation is inevitable. This wasn't a problem in the past due to traffic shaping (p2p is dropped), but that can't be done now.
