[Casper] WEP, WPA, keychain, security

[Thomas Larkin]

Soooooooo

Another project on my road map is to migrate everything to WPA.  Of course I need to test this out, and am looking to push out a package via casper that will migrate clients from the existing wireless encryption to a new one, and probably a whole new SSID.  I have been researching it, and it seems that the security unix command can be used to add, modify, etc keychains in the system.  

I found some apple scripts that do it as well, but they run in the GUI, are interactive and can be interupprted by the end user.  Something I am not really keen on using.

What are the methods you people used with Casper and pushing this sort of stuff out?  I have been playing around with networksetup and security binary scripts to add the network settings and the keychains.  

Thanks in advance for any help
