As part of your anti cheat initiative, and part of the game mode set up, why not have the server store virtually all settings. Mainly the only thing I can think of at this point would be game speed. That way MTA doesn't just read what is going on, it will have the ability to write as well (thus stopping some obscure hacks). This could also (in the future) allow for server side mods that all clients will sync to when they connect (not content like new cars, just things like faster cars for stunts, or 2x gamespeed for insane-o mode...) Also, please reconsider the use CRC. This is very easy to fake, and if stopping cheaters is your goal, this will be circumvented far too easily. Consider MD5.
