It is not the exact situation, in reality. Yes, for the argument of "outlets" it is the same situation, and if they are billing per outlet, they they ought to bill for one. If you can succeed in getting them to bill per "appliance", all the better. The reality is that each cablecard or cable box (known as an access device) takes up one entry in the authorisation system, and that has a fixed cost. See "reality" above. There is a fixed cost for having something authorised.
