Idle users alpha'd out in contact list?

[Alexander Golec]

Hey all, 

	I've noticed that the facebook chat plugin gives no indication of when users are idle, unless they are 1. listed as available and 2. actually idle. Since there doesn't seem to be a way to divine idleness time like there is in aim, there is also no time next to their name. The result is that there is no way to tell if someone is idle except to mouse over their name. 

	I'd like to fix this, and I'm like to know where to start. I assume there is some place where global status is determined, and if there is, I'd like to interface it better with the facebook plugin. 

	If there are other protocols where this is an issue, I think this idea could make them work a little better as well.
