You misinterpreted most of my questions :/ 2) I'm asking if the device can open a direct socket to a host on the public internet. Your answer to (1) implies that the device might not be able to talk to anything but amazon's (potentially non-HTTP) servers, but it might just be for MiTM reformatting (like Opera Mini) 4) Of course the device is tied to your Amazon ID. I'm asking if the modem's permanent radio ID is a part of that 6) That feature is for avoiding the use of the modem, not bridging it! It's only a first step towards tethering. By default it lets the Kindle use the PC's internet connection, not the other way around (which is all that I care about)
