Yeah, I have 5 under 1 and, as pointed out above, you only have to worry about the auth now and then with the changes they have made.

1 thing to remember though is if you go to log in and all accounts ask for an auth key just type it into one an dlog in then log out and redo your password on all of them since you're going to have to anyway if you try to enter the same auth code into all 5 clients
