No doubt one of the issues he'll bring up has to do with liability. While it's easy to say you'd like to get rid of infringing content, it's not always all that easy to identify. It's become common to use file sharing applications like BitTorrent to deliver video to paying consumers. If such transactions are mistaken for piracy, and subscribers disconnected as a result, ISPs don't want to be held liable.
To date no label or recording industry representative has volunteered to take on this financial responsibility. This is hardly surprising since the one constant in music ongoing struggle to build a new business model is the position that the financial burden belongs to everyone except themselves.
