Not sure if it would be within the possibilities of this WG to define
an optional public key hash in HTTP URIs. If a link contains such a
hash of the public key of the target this would protect against
attacks from a root-certificate holding man in the middle. It wouldn't
be a full move to a web of trust nor a replacement of the uri-scheme
as with the httpsy proposal just an optional additional security that
works alongside as well as without the PKI provided trust.
