No, I totally misunderstood.

I vibe coded a little tool [0] that can stream range requests from torrents.

It's a little buggy and super rough around the edges, but it's definitely possible because your torrent client can prioritize piece requests and http standards support http range requests, just requesting parts of a document. I lightly tested it with VLC and seeking the playback to the middle of a video
