HOWTO Revoke a key without having any backup of the key pair ????

Interesting point.  However, I think it points to the way out using existing
tools rather than anything new.  Each signer can still revoke their
signature as long as they can be convinced that the original party is this
same person now asking for this favor.  They should have records showing
proof of identity for the original party (photo ID at least) that can be
used to verify the identity of the person who lost their secret key.  At a
minimum they should revoke their signature if they have any doubt about the
other person's key being compromised.  You would end up with a key that
shows revoked signatures.

I'm glad I made a revocation key. But the point that there's no way to
know it's you could be partially wrong.

If I have my key signed by another person, he knows the key is owned by
me. So he should be able to vouch that I own the key. Ofcourse, you
can't trust the signer to be speaking for the real person (he/she could
be speaking for you without you knowing), but maybe something that works
could be devised?
