I sure hope you don't know what you're talking about, because the 922 is gross overkill for the MRV solution we're discussing here. Communication among existing VIP receivers over a home LAN costs nothing and maintains quality. The Sling solution costs a lot, and compromises quality.
Please keep in mind that the vast millions of Dish subscribers haven't a clue of what your are talking about: they aren't going to even begin to set-up a wired or wireless network, etc. That stuff is for the techies here on the board.
Yes, if people want an MRV solution for the kitchen or what ever, assuming that the current option of dual mode STB's can't solve the request, people will be directed towards the 922.
But keep in mind, that I do know many subs who I have told of the cost and DON'T Care. They want a 922 with Sling for wireless kitchen TV, and yes, with the additional cost of the Dish monitor to view it, in HD. They don't like the idea of the AT&T box in the kitchen nor having to have a Tivo in the kitchen, etc. They love Dish's solution. Maybe some here don't, but they are the peasants, and it suits them just fine--without having layout and build a wired or wireless network---AND it is all installed for them without a single router, switch, Cat 5/6 cable, cost of wireless USB for the receiver, etc. That's they way they like it. A solution that a company provides all that is needed (a 922 and the monitor) and the company puts it all together. Yes, people will be willing to pay for it because they will know of no other way (they aren't techy DYI'rs) to achieve it. If people really want it, they, like many on this board, will do almost anything to get it.
I know of what your are discussing, but that really isn't on the masses list. Dish's current dual mode STB's solve the vast majority of the MRV that Dish subs require. They aren't like us on this board who want every DVR viewable on every TV in the house. You would be surprised at how many subs just want TV in the living and one bedroom and the kid or two can have their own. That's it. No, they don't want every STB viewable in every room, "Nah, what for? I don't care about that. So long as I get mine in the living room and my bedroom." And they don't get all lusty, like us on this board, with all the new, complicated, marvelous technology. They aren't interested in any sophisticated MRV and it is they who view MRV as discussed here as "gross overkill." They think we're morons who take TV way too seriously and blow are money on it. They really do think we're idiots on this. And as for the DEMO at Team Summit: we are still waiting for the 222 to have recording to external HDD to be implemented. Don't hold your breath for the server. How many DEMOS have been vaporware? Now, external HDD starts to get the peasants interested.
