Blossom is great. Should we integrate it into nostr relays as a websocket command so you don't need separate media hosts? Or use DVM so you can also pay for downloads?

Same "get blob by hash" command could be used by more advanced structures like merkle trees for large files that can be chunked and downloaded from multiple peers simultaneously like torrents.

Video file in a merkle tree could be used for streaming: you'd publish the latest merkle root every few seconds?
