Or have a look at Fabric [1] which deals with SSH, sudo, passwords, etc. and 
multiple hosts so it would be a matter of:

  @hosts('192.168.1.1', '192.168.1.2', '192.168.1.3', '192.168.1.4')
  def some_task():
      put('rootidfile', '~/.ssh/authorized_keys')

and run it as:

  $ fab -U root some_task
