I have multiple devices streaming in notes via notedeck: my samsung tablet, my desktop, my android phone, my macbook, my linux notebook. It will be cool if these auto-sync’d with each other on the local network using negentropy. Since each client runs an embedded relay (nostrdb) then each node can serve requests to other nodes. This would be a good testbed for an initial p2p-style version of nostr. Making it work over a globally routed network is a harder problem, but for local sync it might be useful for quicky getting up to date without needing to ask the outside world. This is a toy version of the idea of ICN: information-centric networking, where any network request can be sourced from router caches on a closer network first.
