Except for the Super Joey, the coax connection for the Joeys never see a satellite connection, just a video stream and ip/internet traffic if bridging is enabled, only the hopper gets the sats.
From the way the joey behaves when I disconnect the coax and reconnect, my good guess is that Moca has priority on the dish streams and uses ethernet as backup.
With Uverse/Prism systems, if you use ethernet only, every port gets bombarded with the video streams and can hose the internet traffic, I have not seen that with Dish yet but like to keep them seperate just in case.
