Friends List - Audio Warnings/Beeps..?

Is it at all possible to have the friends list make a click or a beep whenever a friend is online or messages ones self?

I have about five people on my list so far and it's annoying to have to always hit N to see who is online or not, I'd prefer a sound or a beep or something to identify that a user is online, and a different sound when they message me perhaps?

Is this at all possible?

hmmm....not that i know of but that would be a great feature.

hmmm.
