Claiming that illegal movie downloading is clogging the arteries of major Internet service providers, MPAA chief Dan Glickman has offered to team up with them to squelch piracy. The ISPs' "revenue bases depend on legitimate operations of their networks and more and more they're finding their networks crowded with infringed material, bandwidth space being crowded out," Glickman told a Washington conference on Tuesday, adding that as a result, "many of them are actually getting into the content business directly or indirectly. This is not an us-versus-them issue."
