I have a sqlite 'on top' of a chrome cache filesystem. My usecase is to torrent the database as i also have support for files. The caveat is that i primarily use as a key-value store (the btree storage part of sqlite).
They are used to share structured and unstructured data in a p2p way where a torrent could be a database(structured) or a fileset(unstructured) .
But all of this is part of a bigger project that is basically a new sort of p2p "app browser" with a local-first emphasis but where every app can share its functionality though RPC (locally or remotely) with distribution going over DHT's and torrents.
