Any potential issues with a Hopper w/ Sling + Hopper + Joey setup? I probably won't be able to afford 2 HwS's at the price they are sticking existing customers with, and I am replacing a 722 + 612 +612 setup. I assume the two different Hoppers will have no problems seeing each other and being able to access the programming recorded on each other? And that the Joey will be able to access both? Thanks.
