That would be great if they could do that. I think they would be more likely to make a wire that has two pairs of wires inside of it. I know they make the dual cables to run to the house but if they put all the wires that were needed all in one then that would make for an easier quicker install.
I think we will be more likely to see more dual tuner receivers (and quad tuner receivers) than we will for solutions with two seperate receivers. Maybe then we will have the type of cable with multiple wires as described above when all installs would need those. It would then become standard. It would just be something else that Dish Network could make money off of as they would have it manufactured as they do the receivers and parts.
