Hello there. I work in the tech department at a local private high school and we are an all Mac campus using ARD. We have 3 iMac labs plus all the teacher computers that we control with ARD. While I am not a unix guru or command-line expert in any way, I can offer to help you if you contact me directly.
We have ARD admin running on the teacher computer to monitor and control the student computers. Teachers do not have access to local admin rights, but can view all the student screens and/or keep an eye on what the students are doing. Our tech department can login remotely with ARD to install software, perform updates, restart computers, or "screenshare" to assist teachers remotely. Contact me and I can help you set it up.
