i agree. and at least ldap is *designed* to distribute
information in the network, while ssh is not.

why would a stolen certificate, transmitted in the clear be no
problem? would you encode some special info (which? the server`s
IP?) into the SubAltName to make it worthless for the thief?
the initial cert could be valid for a very short time (the
bootstrap process), but that would just decrease the time window
for an attack.
Would you move/copy the servers` private keys (which were needed to
generate there servers` certs) onto the servers once a privat
channel is established?
