It isn't worth the work, MTA:SA is actively working against hacks.
They got their kernel driver in place also, it's possible but it's just not worth the time for public hacks.
As soon someone get's his hands on it the MTA:SA team is patching it.
And even if you get a long "standing" public hack, the chance that server's are detecting it is hiiiiigh as MTA:SA has deep client implementations for servers, basically means every ac (if a server has own) is usually different and efficient.
