I don't think you are that unusual at all. One of the things we have all forgetten in waiting for the ViP922, is EchoStar makes the ViP922 and wants to market the device to more than just Dish Network. Customers like you is just what EchoStar is targeting the ViP922 too.
I may be somewhat unusual as I have FiOS for internet and Dish for TV. My 622 is already connected to the router. It would be a simple matter to swap that out for a 922. I have been waiting and hoping for one. Might wait for the bugs to get worked out though.
You take off the Dish logo and just leave on the Echostar name, Cable, Fios, and other endusers wouldn't know, and could careless about who makes the ViP922, just that it has the features and supports thier provider of choice.
Benefit is Echostar market share will grow, and more marketshare is more money.
