I ran a standard receiver and a wally at the same time and could change channels as desired. So I don't see why you can not run two wally's. If you are thinking about wally as a receiver as I did, remember you need to spend an extra eight bucks or so if you want to record a program and you can only record one at a time. Also if you want the option to pause and skip commercials the Wally wont do it. None of this was told to me when I jumped the gun and bought one. I posted a question and allot of guys are buying older receivers and using them in their rv. Dish will tell you you are not supposed to use the house receiver in your rv but they still turn it on and off for you and trouble shoot it when called.
Good Luck and keep us posted please. "Q"
