I'm Sorry, I Was AFD. ;)

~Ever had to go somewhere while playing SL and you don't want close the app?
~Have you ever left and came back to see people were messaging you or were talking to you but you had chores to do?

If you answered yes to any of those two questions, you may find this idea to be very interesting.
What if there were a symbol/sign that said "AFD" next to your username that would indicate that you are "Away From Device"? Wouldn't that let players know your busy doing something, although your avatar is still logged on.

Example:

Eyeless (AFD)
(Genocide)

Any thoughts on this idea? Feel free to agree or disagree with me. :3
