MPAA to FCC

The MPAA is concerned that network neutrality rules might bring an end to such beloved technologies as digital watermarking, deep packet inspection, acoustic fingerprinting, and content filtering of all kinds.
The MPAA's concern is not with winning any sort of broad ideological ground in the debate over how the Internet should work, but to make sure that ISPs can "manage their networks to protect intellectual property in order to best serve the interests of content creators and the content-consuming public."
Going beyond the specific technologies listed above, the MPAA believes that ISPs need to have the right to control traffic shaping, quality of service guarantees, latency, and bandwidth hogging—all of special concern when it comes to regulating P2P traffic.
