The 'action stream' proposal that I made a while ago takes care of this.
Basically instead of getting the client to send field updates, it requires
the client to send all player actions that affect the state of the game.

In effect, the server is maintaining a copy of the player's field, and
manipulating it in parallel to that which is on the client.  (this is
quite easily done if the client and server is built from the same source)
If the fields goes out of sync then it is likely that the player has
attempted to cheat.
