 well, the clients are all displaying these round trips now.. but they color stuff wrong, 400+ is red. whereas i consider 400ms round trip to be responsive from time connection initiated, to receiving a small req result.  400ms/4 == 100.  a typical 'ping' from west coast us to east coast. 
 Productivity soars when a computer and its users interact at a pace (<400ms) that ensures that neither has to wait on the other.

 yes, and clients can account for this by showing really cool graphics about the connection status 😎 
 IMO if it's under 200ms it's laggy, but i'm an FPS gamer :)
