  The problem there is the same as with windowsupdate - if one can spoof the

  So far, the closest thing I've seen to this concept is the ssh

  copied to every targethost:~root/.ssh/authorized_keys2, such that
  commands can be performed network-wide from a single station.


Do you even read what you write? How does a host with root access to
an entire set of hosts exemplify the least privilege principle?
