>Agreed but usually only power users would be capable of understanding that. In my organization I would put the "power user" label on 1 in 100 people. That leaves 900 desktops. Your org may be different.

You can do it easily through network login script for a group of users. I did such a deployment several times and never been at those 100-200 desktops. :)
