Blizzard has stated that they are replacing traditional LAN with a new system involving B.net. This is meant to be an anti-piracy measure: Basically, they are forcing you to connect to battle.net to confirm that you have a valid CD-key, then you will be able to directly connect to the game host via the local network. This means no lag and no hassle of a password. If you have watched any of the interviews you would know Blizzard is making this game with E-sports in mind, so they would never release Starcraft 2 if it would hurt their chance to attract those gamers

A large % of people that pirate games are what we call casual pirates, in other words people that just go to a torrent and down load the game.  They do not have the skill to hack the games themselves. 

So to recap: There will be no lag

I posted a new topic cause the one on the front page is miss leading.  It makes you think that Blizzard is not going to have a "no lag" gaming option.
