So, I am planning a couple of additional Education FAQ write-ups. The next on my list is BitLocker, I just haven't done the work yet. I am also planning a write-up on deployment that is specific to Education. In the mean time, I found a great screencast by Keith Combs if you would like to see an overview of the imaging technologies. Very cool! Great CSS on his site.
