I haven't called to upgrade yet, but I will be needing a 2 hopper / 2 Joey system. I assume my EHD will connect to a hopper. So does that mean I could connect a 2nd EHD to the other hopper? If so, would I be able to access both EHD's from any Joey? And also from either hopper once the new software is released this summer that allows the hoppers to "talk" to each other?
