I really wonder how this will work with VAC bans and cheating. You can be banned from a game by various means VAC is one of them and Battleye is another popular tool. If a person gets banned from DayZ then they sell their game to buy a new copy that isn't banned does the buyer of their original game remain banned?
VAC bans are account based and can impact multiple games at once. A new user installing the software couldn't be tied to that account. The original user is still banned. That said you might be prevented from reselling as a form of punishment. I'm guessing that it wouldn't be difficult to set up a new account, however it couldn't be associated with the same MAC addresses.
