Umm, yeah, no it's not, and apperantly you didn't read back but we went down this road already. Let me recap for ya.
Cell phone=mobile, was designed that way for that specific purpose. Satellite receiver was not. Yes you can do it, but that is not what it was designed for nor does it automatically give you the right to do it. Direct and Dish did not come along to make watching tv mobile, it came along to give you a better product and a better option than cable. It's a simple concept really, two locations, two accounts. Doesn't matter if you own them both of them or if you own one and your girlfriend, boyfriend, significant other, "roommate", live-in partner, actual roommate, or whomever owns the other. If you put up a Dish to receive a signal at one location and you put up a Dish to receive a signal at another (be it the same dish you carry with you or a different one), then you get to have two accounts no matter what you do with the receivers. Was it always this way, no. But in the last year Dish decided that this was going to be the rule.
