Cheap data transfer attracts trouble, however. 10 cents a gigabyte is much cheaper than buying a CD or DVD, but pirates like to pirate 10x or 100x more than they could ever buy so I think it slows people down.
Circa 2000 when Napster and Limewire were big, Cornell University dealt with it by putting a usage cap on undergraduate IPs and charging for data over the cap. There are some kids who will have their parents pay a few $1000 of parking tickets and data transfer a semester on their bursar bill but it sure slowed the others down.
