I would totaly win this thing if I could participate! Being the author of the Intel AMT DTK, I constently think of new ways I can use (or abuse) Intel AMT. One of my most famous hacks is running TCP connections over Serial-over-LAN allowing an administrator to connect to TCP services on an Intel AMT computer even if the network driver is disable. This demo alone as caused numerous people in my Intel Lab to go WOW! As I would use VNC to manage and remotely re-enable the OS network drivers.
