Suggestion: Logging in as "invisible"

Wouldn't it be nice to be able to log in on any character at any time without all your battle.net friends asking you a bunch of stuff? like: "why u on dat noob char? come raid noob", "come pvp now son". When what you really want is to play the game, undisturbed, going in your own pace, without people spamming you?

I find this annoying, and I think just simple implementations into the battle.net system can make my dream possible.

I believe that people should be able to login hiding that they are online to their friends... a sort of "invisible mode" where you cannot be disturbed. Whether that means a little tickbox when you log in or a status change in-game, i care not, but I think it should be implemented.

Thoughts?
