Today, I was sitting in lass pondering the idea of server side scripting.
It would work something like Mods do, where people can write server-side scripts (plugins) in Lua.

Benefits
» Allows for a more creative ideas and functionality
» Aids servers like bet servers and ES Events directly (and any server, really)

I feel like this should've been in the game already, big games like Minecraft, Garry's Mod, etc. have this sort of functionality.

EDITS
I wanted to include some things I feel that Serverside scripting should be able to do.

» Allow GUI stuff on a serverwide scale AND playerwide scale (so i could draw a rectangle everyone could see, or only some people could see)
» Allow the ability to chat, listen for commands, and add hooks

LUA mods were going to happen years ago, but it was scrapped early on due to problems syncing clients with the server

Right, that was way early on. Surely it could be implemented now, and should be because that'd be fuckin' great.
