The roots of Autokick are in a tool called RCon Commander, by Will Lowman. This was a tool for Q3 that allowed admins to send console commands to a server without needing to join it as a player. Will had made his source code available to the world and it demonstrates how to talk to a game server.
However, MOHAA used a different OOB packet header than Q3 and the information was not publicly available. Crow King was able to hack the packet header out of the server stream and suddenly Autokick became possible.
Since then, Autokick has been through two minor revisions and downloaded over 40,000 times. Also, the MOHAA packet header was published by CK for everyone to use. Now, almost every MOHAA and MOHSH server runs Autokick.
In addition to Autokick, Crow King has also published CKR (realism mod), the MixMaps mod (a mod for mixing game types) and an unofficial binary patch for MOHAA to remove server spawning glitches.
