Do you have any opinions on how hybrid nostr/pear apps might work? DHTs are ok for indexing, but can't hold all the data. Maybe pear could be used to replicate indexes of the nostr network (i.e. kind 10002 and maybe kind 3's, what purplepag.es currently does). Nostr keypairs could also maybe be used along with that index to bootstrap p2p DM channels. But does pear work offline? IOW, to receive a DM both peers would have to be active I assume. So nostr's relay idea could be used to bridge the temporal gap between peer availability.
