Signed response

The PKIX WG has a Online Cert Status Protocol (OCSP) proposal where
the CA runs a service like this answering queries about the status of issued
certificates,
signing the responses.

The concept of signed response by the CA (in this case, registry /
registrar) may be
an important requirement for whois and status request on provreg.  The
reasons are:

1. Result of whois & status queries have been used by lawyers as evidence in
court of law
2. Authenticity of content - client can verify the integrity of the answer
(important data to sign
would be 'Database-updated-date', the query result, or
'No-such-record-at-this-time').

Maybe we should consider this part of the requirement.
