There is no reason we should sit around worrying about HBO. HBO pays people lots of money to figure out how to monetize their entertainment. Let them figure out how to monetize BitTorrent and similar P2P systems. If they choose instead to ignore those technologies, well, they can suffer the consequences when someone else figures it out. The rest of us should not have to worry -- we do not worry when we turn on the radio or use a VCR, so why should we be so concerned here?
