This is true but you should probably define your network size. I don't see
many/any independents doing this because of the cost of the boxes and
dealing with the content providers. If you're a large MSO (say top 15)
then I can see it with today's technology, but even those guys seem to be
moving in other directions to get out of the provider controlled set top
box model.
