With this much traffic MoCA seems foolish. However, perhaps it is more capable than I give it credit for. I would move all inter-receiver traffic to an ethernet network. Put the Hoppers and Joeys on a nice gigabitswitch. I have been running my SuperJoey over ethernet for about 16 months, without a single issue. To do so, I disconnected the MoCA feed from the Coax, so it is just receiving the feed from the Sat.
