If you really don't have a need for that many simultaneous streams, then it seems you have more hardware than you need -- and you could save a lot of money getting rid of a box or two.
FWIW, I get the impression a lot of people have more DISH hardware than they really need.
You're confusing wants/desires with needs. I want to have Dish programming in at least three rooms and I want PIP in at least two of those. So a 722, a 722k and a 211 (for now) is what I want (have). And I dont want to string wires everywhere either. So wireless would be a big help and can minimize receivers, but not necessarily eliminate.
If someone like me wants that much equipment, then we can't complain when fees are added or increased that relates to the number of boxes in the house. Dump equipment, or reduced programming, like I will be doing, to let Dish know I don't appreciate the increases. Bye bye Fox Sports package and probably premium movie channels. Followed by a letter to Charlie that says "Raise my costs and I will keep cutting back."
