  What's not elegant about thinking about things for more than 2 seconds?
If you are making a client/script anyway, why bother the server about some
functionality that can be accomplished quite simple anyway?
  Maybe Kasi could comment on a solution like this: Assume we send a PING
every 10 seconds.. every time we send a PING we push a timestamp on the
"stack". When we get a PONG, we pop the oldest one.

       stack:

PING   (+0)
 PONG  ()
PING   (+10)
 PONG  ()
PING   (+20)
PING   (+20,+30)
PING   (+20,+30,+40)
 PONG  (+30,+40)

Wouldn't this work? Or what am I missing?
