i would love a self hosted sheets. not sure i would use nostr for the backend but fuck it maybe why not.
My main concern would be lack of strong consistency on an application type where consistency is expected when collaborating with multiple editors. If you’re doing accounting, you don’t want your numbers to be off because an event could not be fetched from a relay. But cool concept and might still work under certain circumstances.
probably would want all accountants to be using the same relay, maybe multiple relays for redundancy
