Fencer: Go is coming! This is truly good news. Can you tell us which rule set (Japanese, Chinese, American,...) will be implemented?

Is it necessary to have the code detect live and dead groups? Even if all stones were counted as alive, in practice this would just require the players to contine playing until any dead stones were captured. Better yet, you could use the procedure recommended by the rules of the American Go Association, in which each player indicates which of his opponent's stones he believes are dead, and if they disagree, they play on.
