I don't think it does, I tried it for my cousin and his dad and I gave them my account info they logged into mine on their 360 and downloaded the map pack and played a round on my account then quit and logged into their account and when they started cod:waw it said something about the DLC being corrupt, thought maybe it was just a normal thing as downloads do corrupt I guess every once in awhile but he downloaded 2 times and it said the same thing until he went back onto my account it let him use it but on his account it wouldn't.
