Exiting a kiosk browser with a script?

Hello -

I hope you all can help me with this. I've not had success myself.

I'm running a webpage in a kiosk mode. I need no interaction with the page - it's just informational - I don't have a keyboard or mouse attached, nor do I want one. I also want the computer to start up and shut down automatically using the energy saver preferences. There's no problem getting the browser to start up and begin running. I just add the application as a login item.

The problem comes with shutdown. Every kiosk browser I've tried (Opera, iCab, Plainview) requires a log-out command (Cmd-/, Cmd-shift-K, etc.) to get out of the kiosk mode to quit the application. Without the application quiting, of course, the shutdown won't complete.

Is this something that can be scripted? I don't know Applescript, and the Automator version in Tiger doesn't have the "Watch Me Do" feature that I could find.

Thanks in advance for any advice that you have.

Patrick
