Correct.  That's why I'm suggesting it will go over routers.  However, it is 
out-of-band because the sender and receiver are operating on their own.  They 
both operate with regular traffic pushed to it by the operating system + apps 
running, but they are also operating in this way outside of that by issuing / 
responding to requests on the out-of-band traffic.

The OS and apps would never know a machine is being queried by vPro.  They 
would keep on running like normal.  It's all happening at a layer invisible to 
any security software running on the machine.  That's my point.

Best regards,
