So, I have 2 boxes... and am very much interested in starting to 2-box WoW, but I'd really like to see a confirmation somewhere from Blizzard that key broadcasting software isn't considered "3rd party software" that can be a bannable offense. I've put FAR too much time into the game to be banned for something stupid.

Has anyone been known to be banned for this? Is there a confirmed place I can see Blizzard commenting about this?
