Lua is great. I've been using it a lot with nginx (OpenResty recently) to do advanced routing and header management, and half the time it makes more sense than nginx's own instructions. I know nginx recently released nginScript (JavaScript) but I doubt you'll see Lua in nginx go anywhere anytime soon. It's very much one of the reasons I chose Redis for our caching layer. Yeah, Redis is pretty awesome on its own, but Lua scripting really extends the possibilities by a large multiple.
