I asked our Intel guy about it once. After you've dealt with vendors and sales engineers for long enough, you start to learn to detect when they have no clue how one of their offerings work. I'm not sure that I've ever heard so many non-specific comments, meaningless buzzwords, and attempts to redirect the conversation.

I didn't get it even a little bit until I found an open source project based on Intel AMT, and that's apparently just a piece of ME.
