Well I think you could somehow make it possible to identify the KS server on the GiP List (with a specific server name perhaps, or some weird character in the server name that JJ2 doesn't support). All the utility then has to do to check if someone's hosting is to load the GiP List and look for it.
But of course you could also do identification on a 'deeper level' (if that is easier or more secure) by requesting the game data directly from the servers on the server list just as some GiP scripts do.
