You don't need to physically bring it, right? You can just have somebody buy one for you and activate it with your serial number.
Similar question: If somebody else gets you AppleCare (say they are eligible for student pricing), can you still use it on your own computer?
I know that's getting close to fraud in moral sense, but as long as AppleCare is bound to serial number, not person, it shouldn't be a problem, right?
