    If you are on a host that doesn't have the public key of remote host then you wouldn't be able to connect.

    Code:
    AUTHORIZED_KEYS FILE FORMAT
         ~/.ssh/authorized_keys is the default file that lists the public keys
         that are permitted for RSA authentication in protocol version 1 and for
         public key authentication (PubkeyAuthentication) in protocol version 2.
         AuthorizedKeysFile may be used to specify an alternative file.
    
         Each line of the file contains one key (empty lines and lines starting
         with a '#' are ignored as comments).  Each RSA public key consists of the
         following fields, separated by spaces: options, bits, exponent, modulus,
         comment.  Each protocol version 2 public key consists of: options, key-
         type, base64 encoded key, comment.  The options field is optional; its
         presence is determined by whether the line starts with a number or not
         (the options field never starts with a number).  The bits, exponent, mod-
         ulus and comment fields give the RSA key for protocol version 1; the com-
         ment field is not used for anything (but may be convenient for the user
         to identify the key).  For protocol version 2 the keytype is ``ssh-dss''
         or ``ssh-rsa''.
    
         Note that lines in this file are usually several hundred bytes long
         (because of the size of the public key encoding) up to a limit of 8 kilo-
         bytes, which permits DSA keys up to 8 kilobits and RSA keys up to 16
         kilobits.  You don't want to type them in; instead, copy the
         identity.pub, id_dsa.pub or the id_rsa.pub file and edit it.
    
         sshd enforces a minimum RSA key modulus size for protocol 1 and protocol
         2 keys of 768 bits.
    
         The options (if present) consist of comma-separated option specifica-
         tions.  No spaces are permitted, except within double quotes.  The fol-
         lowing option specifications are supported (note that option keywords are
         case-insensitive):
    Would that work?
