It's not clear to me what a "Prime Controller" is. Is it just a password? Or is it the password plus the wallet containing 125k coins? If it's the latter then it can be stolen. As soon as you "steal" it, you move the 125k coins to a new address that only you control. You didn't steal the password (in that I still have it and can still use it - you only stole it in the Hollywood "copying files is theft" sense of the word) but you did steal the coins.
That's the ambiguity that tripped me in this Cryptsy deal - turns out they got a PC without the coins (BTW they still haven't explained where they would be getting the coins to fill it up), whereas previous "deals" of PC ownership seemed to involve the coins.
