We appreciate #Nostr is a fantastic protocol to share short form #Microblogs and posts (events; twitter/facebook like but better), longer text notes (blog posts), host real time audio conferences (nostr nests). But is there any videoconferencing tool/app built on top of this protocol? The reason I ask is we can use Nostr for Telemedicine/Telehealth applications in resource poor settings in the world and equally in resource-rich settings during emergencies (war, environmental disasters, and others) where events/notes etc can be shared and stored-forwarded through distributed relays and lives can be saved.
Not only that, using zaps and SATS can build a "bridge" between people who can afford (even tiny amounts) to reach supplies and provisions to people who need them most.
Thoughts?
