David, You may want to talk to our lab people here. They have deployed labs of iMacs that dual-boot between Mac and XP, are refreshed on every log out and can receive 'packages' of software on reboot. The only thing we don't yet have is AD, as we are currently authenticating against LDAP. But we are in the process of designing and AD implementation. Let me know if you want me to put you in touch with people here. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ I will be out of the office Dec 17 -19, and Dec 21 - 26th. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Foreign Language Technology http://go.carleton.edu/f Carly J.
