Collider: An experimental Minecraft server

The author posted a thread about this on /r/clojure, giving more explanation and reasoning. I'm very interested to see this expanded to cover the rest of the mechanics. There have been some attempts at allowing modding through Clojure (cljsh is the big one), but built from the ground up in Clojure is new and interesting, especially given the improved performance.

I'm not super convinced by performance arguments of partial reimplementation. Too much room for inability to reproduce certain features with the provided optimisations.
