Hi Holger,

Sorry, I confused public and private in my previous answer.

On the clouds implementing the EC2 API, the user can create a key pair in the
cloud infrastructure, retreive the private key on his computer, and make the
public key available as metadata to an instance he launched.  The cloud
infrastructure guarantees that the private key is never seen by third parties.
It also guarantees that the instance metadata will not contain other public
keys.  This implements a system where a user can start an instance where no
password nor key is stored in the image, and only him can log in a
predertermined account with a key pair he chose.
