Peer-to-peer file trading software, the bane of movie producers and recording company executives everywhere, is nothing new. But the overwhelming epidemic of illegal movie-trading predicted by some has never quite come to pass, mainly because peer-to-peer swapping is incredibly slow and cumbersome for large files like movies. But a new piece of software is changing that – BitTorrent allows a user to download, say, an hour-long episode of The West Wing in minutes, rather than the hours it would take with traditional peer-to-peer software. And if you think this development has Hollywood running scared and ready to fight, you’d be right.
