I've used say on users before as a prank (as in co-workers) and it works. Hmm, when I run a shell script as root the apple script works and it also works when I use the send unix command from ARD admin.

I have not tried osascript over ssh, but let me try it now

Code:

bash-3.2# osascript -e 'tell application "System Events" to display dialog "Hello World!" '
button returned:OK
bash-3.2#

Worked for me over ssh. I have two iMacs on my desk at work and that one liner did it, and when I hit OK on the remote computer it returned back that I hit OK.

The only time this may not work is when the system is at the login Window. Say works too. Though do note that I am ssh'd in and able to sudo so you are correct that you would need sudo rights on these machines.

DESCRIPTION

       ipcluster is a control tool for IPython's parallel computing functions.

       IPython	cluster  startup. This starts a controller and engines using various approaches. Use the IPYTHONDIR environment variable to change
       your IPython directory from the default of .ipython or _ipython. The log and security subdirectories of your IPython directory will be used
       by this script for log files and security files.

POSITIONAL ARGUMENTS

       The first positional argument should be one of: {mpiexec, local, mpirun, pbs, ssh}, which are the available cluster types.

       For detailed help on each, type "ipcluster TYPE --help". Briefly:

	 local	       run a local cluster
	 mpirun        run a cluster using mpirun (mpiexec also works)
	 mpiexec       run a cluster using mpiexec (mpirun also works)
	 pbs	       run a pbs cluster
	 ssh	       run a cluster using ssh, should have ssh-keys setup

OPTIONS

       -h, --help
	      show help message and exit

EXAMPLE

       ipcluster local -n 4

       This command will start 4 IPython engines on the local computer.
