Romio OTA with MINI and MOCA

I am awating the delivery of my Romio OTA purchased as part of the special that last couple of days and have a question. The Romio will be plugged into my network via a gigabit network connection, but I need to figure out how to get a network connection in the bedroom using the MOCA capability. Do I just need a single MOCA adapter and is it plugged into my ethernet switch. I assume the mini has builit in MOCA capabilities?
