Not sure in the case of Croquet, but you can implement this very well with https://reflect.net https://reflect.net (my company). Server authority is a core piece of what it provides, and as a bonus you don't need a special runtime – it runs in plain javascript in a web page. I play Robo Rally all the time with my kids and would love you to implement this. Happy to help any way I can :).
