roamio moca?

I already have a functional moca network in my house. I assume it should be no problem to plug a new roamio into the coax and have it get network access from the moca?



My 2nd, and more important question is, once I have the roamio getting network access from moca, could I then plug in a laptop to the ethernet port on the roamio and would the laptop get proper network access?
