NEW BLOG! After closely following atproto permissioned data, my take: what if an "atproto repository" is the base thing and there's more than one way to sync it? Based on @ipv.sx's take and grounded in a real-world Streamplace use case: how do I make a video private, then public?
What is an atproto repository?

Rashid Aziz: Extending ATproto for private data - ATProto Community
The Atproto Spaces Alpha is Live - AT Protocol
Atproto Spaces, formerly known as “the permissioned data protocol,” is a new extension to atproto that enables non-public data. The alpha is now officially open. Here’s how to develop with it and what to expect as we work towards the full release.

Introductions and kick off
Hello, I’m Simon Horrobin. I’m working on a couple of projects which are ATproto relevant… one to handle sport and health data, the other for managing publishing workflow. Both of these need privacy to varying degrees. I think about this in a few axes… who can create, view, edit, delete, grant, revoke, all over time and state.
What is atproto?
What is atproto? atproto is two things: A protocol for creating open social networks An open social network atproto, the open social network Today the atproto network has 36+ million users and powers Bluesky and a handful of other apps. Almost all atproto data is public. Content like posts, likes, follows, and photos/videos are publicly accessible to any network participant in a permissionless way. As an example of how open the network is, here’s how easy it is to stream all public data on the network using a public atproto Relay like bsky.network:

Permissioned data on atproto — pick your depth
A private room in a place with no walls: how engineers are adding permissioned data to atproto. Read it plain-language or technical.
The promise of ATproto is social media without corporate overlords
Anyway, this is mostly for my friends, but I kinda love the model of “broadcast on atproto, but transfer data privately off protocol”

So @iroh.computer is kinda magic. This turned out to be a huge project, and I'm still reducing the overall complexity, squashing bugs, and cleaning things up, but uh, the endpoint discovery works pretty seamlessly and I can view and download items from another users library in a pretty simple manner
