Servers already have to track all presences. When it receives an
unavailable it has to broadcast it to all the places the user sent
directed presence. If some servers aren't doing this then I can
definitely see why you guys see a lot of ghosted users. :) The only time
I really notice it is in the s2s case when a server goes down.
