I believe it would be a great idea to take into consideration adding an anticheat to the open.mp client. Aiming hacks are a huge issue currently and a lot of servers already adopted clientsided anticheats like whitetiger's or sampcac. In the beginning, I am sure that adding natives for small checks (like returning a list of injected modules into the gta_sa executable, or checking the md5 hash of a local file) would help us greatly.
