    I had the same problem as you at first. (Obviously, script-tameness
    wasn't a design-goal for any of the SSH protocols.)

    Then I searched, and followed the URL:
    http://atoms.vuse.vanderbilt.edu/Elements/CompMeth/Comp_Methods_ssh2.html

    I followed the instructions there to the letter, using <ssh-keygen>
    to generate the public and private key.

    The private key was saved onto "${HOME}/.ssh/id_dsa" on my local machine
    and the public key was saved as "${HOME}/.ssh/id_dsa.pub". I did not
    enter any passphrase (because as we both know, that isn't acceptable for
    scripting purposes).

    Then I went into my home directory on the local machine, and typed
    the following commands

    %> chmod -R g-rwx .ssh
    %> chmod -R o-rwx .ssh

    After that, I entered the ".ssh" directory, and then used SFTP to
    upload the "id_dsa.pub" file into the *remote* machine's ${HOME}
    directory, labeling it "tmp.txt" using the following command (after
    logging on via SFTP):
    > put id_dsa.pub tmp.txt

    Then I connected to the remote machine via SSH (shell access)
    and typed the following commands:

    %> mkdir -p .ssh
    %> cd .ssh
    %> cat ../tmp.txt >> authorized_keys
    %> rm ../tmp.txt

    That way, my local "${HOME}/.ssh/id_dsa.pub" became one line on
    the remote macine's "${HOME}/.ssh/authorized_keys":
    And ever since, I've had no problem.
