How do you think it's cheating? If the user buffers everything up to
the end. If the data receive the server too late, he is bad off.
Also, his commands can fail. Movements can fail due to ZOC. And this
happens in battle where you may think it is an advantage to batch the 
move requests. In any case, he must process his batch before turn done.

Do I miss something?
