[racket] universal Pong question

The thing is, Battleships isn't real-time, so I'm not sure it would
have the same issues with when it's appropriate to send info across
the network. The board in Battleships only changes when someone does
something--there's no (on-tick ...) action to worry about.

But send it along--examples are certainly helpful.
