@s0 There should be a few options with varying complexity.
I'm not familiar with the current state of things, but probably would go into two directions:
Have something chop the stream into chunks for DASH or HLS. Potentially ffmpeg. To avoid constant bandwidth use you could have a local HTTP server that hosts those and a caching reverse proxy on a server (exclude playlist from cache!).
Something really simple around Icecast and (on-demand) relaying. "Legacy" mode where just passes bitstream.
A nice little Mastodon instance. Mild trolling encouraged (keep it local), but not required. Malicious behaviour is not tolerated. Follow Wheaton's law and you'll be fine.
