Cool. But this doesn't sound like a typical normies' scenario :)
Discussion
using computers without internet? Most of the apps on my computer and phone are designed to work without an internet connection. You’re dooming all future nostr apps to be online always.
I agree that an offline-first approach is superior, and often needed, also to cover areas with poor or instable connectivity.
But is the signature really needed when the user is offline? Or should he be able to manipulate the content, and the signature can take place as soon the connection is restored, before the event is sent?
An interesting idea, but it seems like complexity for complexity's sake
