I was doing that for a while, and running a seedbox. However, on occasions when the seedbox was the only seeder, clients were unable to begin the download, for reasons I've never figured out. If I also seeded from my desktop, then fan downloads were being fed by both the desktop and the seedbox. But without the desktop, the seedbox did nothing.
I need to revisit this in the next few weeks as I release my second record (which, if I may boast, has an incredible ensemble of most of my favorite bluegrass musicians on it; it was a really fun few days at the studio).
Currently I do pin all new content to IPFS and put the hashes in the content description, as with this video of Drowsy Maggie with David Grier: https://www.youtube.com/watch?v=yTI1HoFYbE0
Another note: our study of Drowsy Maggie was largely made possible by finding old-and-nearly-forgotten versions in the Great78 project, which of course the industry attempted to sue out of existence on an IP basis. This is another example of how IP is a conceptual threat to traditional music - we need to be able to hear the tradition in order to honor it.
