The way they work is by changing the MapInfo file (inside the map mpq) which holds the lobby informations (default AI in this case). So it's not really hard to do.
However if you are about to change the team information, it's going to be harder as it does not belong to the map file but you have to change the Starcraft memory.
While here on mapster we encourage you to do 3rd party apps that interact with the game in order to provide better mapping tools, the launchers are primarily used by people to play without buying the game. Therefore this is under high surveillance by Blizzard and we don't want to have problems because of that :)
