Hello, I was following the discussion on Reddit related to Privacy on IPFS and it that led to me wondering if anything like access control for pinned content would be possible. I am thinking in something like having control over my IPFS node to select content to be public or "protected", where the node can distribute public content without any sort of authentication while protected content would only be served to nodes that I deem to be "trusted". Is this something feasible/planned for the protocol? More details below: https://www.reddit.com/r/ipfs/comments/b9s24g/ipfs_privacy/ek82l0o
