I really like the idea. They need to find a way to make the new two games (diablo 3 and SC 2) playable even when you keep your WOW account up and running.
Looks like a good plan, for wow only and for D3 and SC2 too.
im only concerned about giving my name away to everyone. I may want all to be able to contact me even if im in another realm/game. But going thru my real name, wich probably means the name of the account owner (Credit Card owner?).
What I read is that you must accept your friend as a "Real ID friend" before this working, unless both of you accept the request none of you will have this feature activated with that player. If both accept both will see the real name of the other.... or that is what I understood in the blizz page.
