I don't think AMT lets you bypass a supervisor password, so you'd have the same problem there. The point I was trying to make (not terribly clearly) was that it doesn't give you any means of persistence that physical access wouldn't also give you.

True, there are some niche configurations where you wouldn't have to worry about this.
