Actually, when gingerbread went live verizon started putting a block up asking you to buy their tethering package. They didn't ask for any restitution so I think its safe to say they aren't too concerned about it. I also notice that the new Bionic dock has usb ports for a keyboard/mouse and it has a mirror mode......isn't that same as tethering?
Could be, and if they are like AT&T with the lapdock they will want to charge a tethering fee.
