So I am guessing the tool you're making makes it possible to connect to servers through WC3 maps that are coded in LUA? I am also guessing only the host needs to be running it, and that the database credentials are stored in the tool, not in the map?
If so I can see a plethora of new stuff coming. SQL based save systems for RPG maps, rank systems and leaderboards, in game credit systems with currencies and so on.
