Chained Ogg FLAC works really well as an intermediary/internal streaming format.
In my case - I have an internet radio station available in a few different codec/bitrate combinations. I generate a chained Ogg FLAC stream so I have in-band metadata with lossless audio.
The stream gets piped into a process that will encode the lossy versions, update metadata the correct way per-stream (like there's HLS with timed ID3, there's Icecast with chained Ogg Opus, Icecast with AAC + Shoutcast-style metadata).
