[Casper] Changing wireless settings across a number of systems

[Cory Ranschau]

We've got a test lab of systems that I'm trying to change the wireless settings on.  We are changing from a problematic PEAP setup to a PSK environment.  Systems are configured with Parental controls and Simple Finder.  They are unable to change anything in the Control Panel shy of the screen saver.   Building a package to be deployed by Casper grabs the system.keychain file which is bad news for all of our existing systems as pushing a package with this seems to put the target machine in a very difficult to remove loop of removing the keychain, and manually adding in the settings physically on the machine.

Anyone found a way to get around this?  I'd basically need to push wireless settings across the command line with a script that uses that password with networksetup or find a way to push the item into the keychain from SSH.

Something like step 4: here has potential except for the fact that it must be run as the currently logged on user and our lab user cant access the Network settings.

Thanks in advance!
