That's almost what TimBL's other project does, Solid: https://solidproject.org/ https://solidproject.org/ Sans the encryption - it's been looked as, IIRC, but not there yet. I'm not sure whether that would actually make it easy to revoke access though; as soon as someone has a key to decrypt it, they can just copy the decrypted information elsewhere, right? (Disclosure: I work at inrupt, TimBL's startup that exists to stimulate Solid adoption. Opinions are my own.)
