Software authenticator might be different and not have multiple serials, in that case it would suck.
This is what I'm talking about. Hardware is tough to reverse engineer. I bet my left one someone will break Blizz's app very very soon. It could be worth a fortune to the "gold sellers" (aka steal your account when they PL you and then sell off your gold and toons because you gave them your info).
As said above - good security doesn't rely on "crackable" software - the software should generate a unique private key that you would need to get.

Now I suppose having a worm that would hack and get your private key and send it to some site where it would be harvested ... that's possible (I expect the app to store the private key in a mac like OS level keychain; but if it can be retrieved by the software it can be retrieved by a hacked application... so if you see a new "Cool new Wow something" app showing up from unknown source; don't install it on same iphone as your blizz auth one!)
