access control per document

[pgte]

Grant, revoke and verify different types of access to specific humans.

Grant access

As a document administrator, I should be able to delegate access to other humans.

Access types

When delegating, I should be able to specify which type of access I'm giving to another human:

• Admin (become a document administrator)
• Reader (follow the changes of a document in real-time)
• Writer (make changes to a document)

Revoke access

Also, as a document administrator, I should be able to revoke any of the access permissions.

Secure propagation and verification

This access control list changes should be made known to the other peers participating in the network. These changes should be transmitted in a secure way to other nodes in a way that they're able to securely verify that the author of these changes had the permissions to perform them at the time of change.
