LÖVE

I was just curious, has anyone made a game (actually completed, not just some proof of concept) that has WAN multiplayer? I know it's possible, I'm just more curious if it's been done or not.

And how would you handle cheating? It's all interesting to know.

Qcode, an AWESOME coder and friend of mine, made the well-known Mari0 game have an online mode:
Mari0 1.6 (Qcode Unofficial) Online- Released

BUT I'M IN NO POSITION TO TELL WHETHER OR NOT YOU CAN USE/MODIFY HIS CODE, SO ASK HIM DIRECTLY!
