+Finally, publish your signatures back to the keyservers, so that your
+users can automatically verify your machine when they connect:
+
+ $ gpg --send-key '=ssh://server.example.net'

+==================================================================
+
+A host can maintain ssh-style `authorized_keys` files automatically
+for its users with the Monkeysphere. This frees you (the
+administrator) from the task of manually checking/placing SSH keys,
+and enables users to do relatively painless key transitions, and to
+quickly and universally revoke access if they find that their ssh key
+has become compromised.
