Nervous System - Nerves Clustering Using Your Own Distribution
summary
Claims that Erlang R19 custom distribution plus a custom EPMD module lets Nerves devices auto‑connect without DNS or predeclared node names and that discovery can use multicast DNS. Demonstrates a concrete artifact: a distributed blinky (LEDs on 2+ devices taking turns). Local demo connects two nodes on one machine after port/IP hacks; Raspberry Pi Wi‑Fi demo is flaky, hitting timeouts and EPMD/port issues, so solution is promising but not yet robust on real hardware.
