Currently, I can log into my 5 wow accounts, via 5 B.Net accounts, with a single authenticator code.

I too don't think this will last, but I have 5 authenticators now, which will be much faster to log into the game, then having all the accounts on a single B.Net.

Of course, I lose out on all the nice features, such as drop down arrows in account management to switch between accounts.
