I figured this is kind of simple. I want a tool both In-game and out of game where I can specify a "buddy list" rather than using the .f function. In game it could be more than the .sr report in the lobby. Maybe .bl ? Out of game it could be a simple web-page attached to your HTC account that simply displays who is in game and in what arena (the same as the .f command).
The reason I thought of this was due to the fact that sometimes I am 50/50 as to if I'm going to fly and the presence of my buddies can often make the decision for me.
