Add VoIP, and DirecTV has triple play to compete with cable. Add a Sprint partnership (Sprint doesn't do fixed broadband anymore, nor does it do linear video delivery) and you have a quadruple play that both Sprint and DirecTV can cross-sell.
The big problem I can see with this is and always has been the fact that in apartments/condos etc. you can't use dish. And that is where the densest group of customers are located.
