yes, it's a pwa so offline first. it uses yjs with webrtc for p2p generically and the "last mile" will be a "light" electron app that you can use via webrtc to store files .

no technical server, so really the only infrastructure is the signalling, and it's straight forward to scale that.

might still be a niche but it serves my day job needs. field work and reporting asynchronous is a pain.
