We are beginning the development process for transmitting Nostr events in a peer-to-peer fashion, away from relays. This will start with Gift-wrapped DMs, Private Attachments, Private zaps, Private Text Notes, and Private Reactions; and will be the preferred transmission choice if both users are online, falling back to relays when they are not. Our Push Notification system already transmitted over 500,000 GiftWrapped Nostr events that relays will never see. With a full P2P this will get even better and will open the doors for voice and video calls directly inside Amethyst. Side-stepping relays won't be easy or quick. And I am sure we will get strong pushback from relay operators. But we will get there. And while this might start as an Amethyst feature, it will be a NIP and other clients will be able to join the privacy train. 

Nostr is just starting.
