Some time ago Blizzard tried to sue chinese Haofang for allowing gamers to play with non-legit cd-keys. Haofang works a bit like Hamachi - it allows to make LAN games over VPN. Reason why Blizzard lost the suit was that the judges found that cd-keys weren't really Haofangs problem because Starcraft already had a LAN mode that didn't require a cd-key. It might be possible that the number of chinese playing with non-legit cd-keys is too great a problem to for Blizzard to ignore. We still don't know how b.net 2.0 will work, perhaps it will simply add an cd-key check to LAN play (authenticated LAN play?). This would work well for Blizzard, if it want's to cut down on rampant chinese piracy - filing a lawsuit against a future service that doesn't care about cd-keys gets so much easier.

Actually, /b/ is for random. Just so that 4chan wouldn't be considered a pro-shit imageboard, I might point out that there are many other boards, such as music, news, auto and sports to name a few, on 4chan, though /b/ is indeed the most famous of them.
