I'm using a raspberry pi as a low latency server to organize and provide a bridge between esp8266's that are running LP flame effects for Capn Nemos Flaming Carnival. You know, for the kids! I've open sourced various aspects, and though it's all a bit disorganized as it is primarily me that uses it, you can find codey bits at https://github.com/burntech, and cool pictures and links at http://capnnemosflamingcarnival.org. Yeah, it's kind of a Burning Man thing. But long term, I hope the tech can serve as a small fast network that controls potentially timing critical things (eg shutting off fire reliably, music-controlled effects, and etc.).
