[JDEV] Heartbeat patch for dialup and laptop users and faulty presence info

[James MacMillan]

Could you please clarify this for me?
By my understanding, this ping/pong technique only generates extra 
traffic between the client and their
direct server (virtually a single hop). Since jabber is intended to be a 
highly distributed network where
many users administer their own servers, ~14Mb of extra traffic spread 
across the 100s of 1000s of servers
that would be serving those 5 million online users doesn't seem as relevant.
