Note that the Porkhash proposal doesn't use signatures or keys, just an
MD5 hash of items with a secret.  Under the porkhash proposal anybody
wishing to verify a hash has to contact a system which possesses the
secret, for re-computation of the hash to see if it matches.  This
requires the secret to:

  a) be on an exposed system.

  b) be on a system which can be systematically explored and tested in
  attempt to deduce the hash.

Neither are optimal conditions.

I see, I have to admit I had only been following this thread in a cursory 
manner.  I take your points.
Thanks.
