[coreboot] Intel ME Question

Hi,

Seeing that many of you know a lot about Intel's ME I wanted to ask a 
couple of things if its ok.

* Is the ME network accessible on all Intel chips or only the vPro ones 
with AMT?

* I saw an interesting take on this in the link below, instead of the 
usual FUD surrounding this topic whenever its mentioned. What is your 
take on what he says?

(The only correction to what he says: there is no need for a BMC card to 
use AMT because its network capable out of the box)

Thanks.
