MPAA head: Filtering is in ISPs' best interests

As befits a man who has spent years in DC, the MPAA's Dan Glickman has polished his share of folksy analogies to a shine.
His words yesterday revealed that movie execs are thinking about one thing in particular: the technology that can be used to halt film piracy, and that they expect ISPs to implement it.
The MPAA needs the support of those companies best in a position to implement filtering technology: ISPs.
ISPs that are concerned with being, well, ISPs aren't likely to see many benefits from installing some sort of industrial-strength packet-sniffing and filtering solution at the core of their network. It costs money, customers won't like the idea, and the potential for backlash remains high. Should such a system work, it could lower overall bandwidth usage, but whether that would make up for the cost and PR headaches of a filtering regime is unclear. It won't do much for liability issues, since ISPs are already protected under "safe harbor" provisions.
