I had a concept called "Nostr Companion" that acts as a local relay proxy and makes sure every event is only downloaded once; even handles sending to the relays too. Just connect to it, and it takes care of sending a new event to the listed relays. Would just live as a tray applet too.
The iteration would've included nsecbunker support to ultimatively do something like fetching nsecs from an AD to allow whole teams for like marketing to use a shared nsec without actually having the real one and implementing a company local RBAC this way.
Never got to make it though, but it would at least partially reduce the strain on browsers... to a degree, anyway.
