Thanks for the question.
You can certainly re-image a system using Intel AMT. You would need to establish an IDE-R session to boot to a image similar to BartPE (http://www.nu2.nu/pebuilder/)which has plug-in for Norton Ghost that can be used to re-image a system. BartPE is just an example but you can certainly use other ISO images that will let you re-image a system.
There are certain limitations when you are doing an IDE-R/SOL session with AMT. Redirection in graphical mode is not supported currently, so you would need to use an image that can be operated in text mode (non-graphical) for remote re-imaging. WinPE is another popular tool for re-imaging but it needs to be configured to run in non-graphical mode.
Hope this helps.
