DVD-audio was going to be a big thing, but a day before the distributors were going to announce that they would be releasing music on dvd format, some hacker guy posted the coding all over the internet. It's like Blizzard with warcraft 3. They release a beta only playable on battle.net. So what do some hackers in vietnam do? They release a battle.net emulator which has 10 times the people playing on it as the real deal.
I get a kick out of hearing how companies are trying to shut down napster/kazaa/gnutella/etc. Apparently these people don't realize how easy p2p programs are to write.
