A few things...
The folks from DISH were watching your comments and feedback carefully during the chat and they ARE paying attention!
First they are telling me they are seeing what can be done about people with Tailgaters so they don't need a seperate account. (Keep your fingers crossed there guys!)
Now on to a few other things that I got comments on...
1) Two hoppers will be on same network at launch - so use Duo Node - no isolators needed. They will behave like two separate networks and once the new software downloads they will share content. Which means at launch you need two sling adapters also
2) This is not verified yet, however in theory if you use the Hopper Internet Connector - then one connector should give internet access to entire system.
3) When comparing a 722 and 211's to Hopper and 2 (or 3) Joeys you are not comparing apples to apples. With Hopper you are getting DVR functionality in every room, plus all the additional features that the Hopper and Joey system give you including access to Pandora, Facebook and access to you music collections over DLNA. Not to mention all the speed and Prime Time Anywhere. Going from the 722/211 setup to a Hopper Joey setup is like going from a mid range Honda to supper speedy mussle car.
4) Someone said they have one tv and if they can only have 1 Hopper and no Joey's and I said yes... that answer is correct but the way the DISH system is setup you will be charged $10 for the whole home DVR service, its just the way the system is setup. (So my advice is to buy a second TV and get a Joey.)
