I marked 'Other' (along with no OTA and the fee structure) as I would want to control the one Joey from 2 separate remotes and it appears that can't be done. Otherwise I would split the signal from one Joey to the kitchen and bedroom as I do today with TV2 from my 722 and be able to use a remote in either location for that one Joey. Neither of those TVs are used enough to justify any additional fees for me...so sticking with my 722.
Checkout the http://www.satelliteguys.us/hopper-zone/277994-hopper-remotes.html thread it looks like you can have at least three remotes on a Joey.
