The Solution to High Ping-Latency - PingBall!
PingBall
Pingball creates a second ball along the same flight-path as the first, 'normal' ball. This second ball (Pingball) is delayed by the pingtime between you and the opponent. (The ball is generated upon the opponent's ACK of your paddle-ball collision.) This means that on normal high-latency play, you should notice that the Pingball is always hit by the opponent's paddle correctly, regardless of the latency between the players, whereas the first ball would've played-out the original interaction with the table/environment (thus double bounces/hitting the back wall, etc.)
