This is like Dish, which makes the equipment for expressvu. They feel that anyone needing more than 6 receivers can well aford to pay for a second account. This is to keep a neigborhood from setting up one at each house with one account. As they perfect using the A/C line to hookup the telephone, then they may extend the amount of receivers that one account may have. It may also be a limit on their software that they designed in the begining also.
