I'm absolutely sure that Blizzard would use some form of verification that utilizes a computer's MAC address (or MAC addresses), public IP address and possibly the LAN IP address coupled with some sort of hash sent from the server back to the client from the last successful login using the authenticator. I'm also sure they would allow users to have to opt in to this instead of out (and be able to do so).
I'm absolutely SURE about this, because that is what I would do, and I would hope the minds at Blizzard get paid more than I do and know more than I do. I would hope.

That's a terrible comparison.06/16/2011 04:40 PMPosted by FizzlepickWe’ve recently updated our authentication system to intelligently track your login locations, and if you’re logging in consistently from the same place, you may not be asked for an authenticator code.
This is kind of like an anouncement from bank of america saying they've updated their ATM's to "intelligently" know that it was you that input the ATM Card and no longer require a PIN for withdrawals.

Yes, but naive developers consider them unique serial numbers. So theoretically the WoW client could read the MAC address of your NIC and transmit that as a pseudo-serial number.
