You can't play either SP or MP without logging onto Battle.net each time you start up the game. I think that answers your question.
Plus, piracy of games is bad, mkay? This isn't like pirating music where they have concert tickets and other avenues to fund their operations (not that I'm condoning music piracy either). But with game makers, sales of games are their ONLY source of R&D money. Sales from SC2 will fund the creation of the next great Blizzard game. Pirating SC2 is a very selfish thing. You'll undoubtedly play WC4 or whatever the next great Blizzard game is, but if you pirate, you've having everybody but you fund the development of that game.
would like a word.
