both of which can be 'denied' by the original sender, and can be proved by
the forwarder, only by having someone witness the decryption.

I've never put very much faith in the screen eyes-only thing for that
reason. What is the point? If you don't trust the person, don't send the
document to them. Once they have it it's their choice who they forward to,
and it's now out of your control. Tough.
