"To solve this problem I wrote a simple server that runs in the cloud which can handle any number of realtime broadcasts uploaded using a simple curl command. This allows you to essentially broadcast radio feeds with a single line. My solution to the problem of broadcasting audio without port-forwarding was to create a free and public “dummy” server that handles any incoming traffic and forwards to any number of connected clients. This server keeps track of connected clients and routes incoming packets to them, otherwise discarding the packets."

If the author had perhaps titled their post "I wrote a multiplexing server for audio streams" it might go over better, although that doesn't have the proper click-bait appeal.
