I'm going to do.a zap.stream test run in the very near future, try the stream forwarding feature to PeerTube, maybe also JewTube at the same time, see if it works.

I don't like the crux of the whole thing being a non-self-hosted service, but at the same time I realize I can just submit a feature request to PeerTube & see if they can't incorporate the same feature... ffmpeg is a dependency already, that might be doable. Hell, even if only as an optional plugin.
