Terry - I think that active screencasts showcasing some 'how to' scenarios would be excellent. Reading manuals is mandatory for end-users to setup environments, but 'seeing is believing'.
I'm pretty sure different ISV's have some demos on their sites, it would be great to pull the vPro based ones into this site.
Links such as Preparing the Environment for Out of Band Management Solution with Intel vPro AMT Technology have mutliple stages and would be a great opportunity to 'share the experience' for others.
There are already some great audio/video blogs about the Intel AMT DTK - I'd say, let's keep this momentum going!
I'd assume that most IT guys are pretty busy, and multiple shorter screencasts would be preferable to a few longer ones...
