Intel has been hyping their vPro technology on laptops and desktops as
being capable of doing this securely. The catch of course being that
you have to have the hardware which support vPro. In our discussions
of doing this we were toying with the idea of blocking all packets
except those that came from a specific IT centric address range. That
discussion though did not get very far out of the theoretical arena.
