Yes, that's correct, and yes for Ethernet. There may be USB ones too, I haven't seen any.
I'm not looking to install any wire.
To clarify - The DirecTv and TiVo units need a phone connection or network connection to talk to their servers. I was looking at a network connection because my Tivo and phone lines are on opposite sides of the room.
HomePlug stuff should work fine -- as long as the electrical wiring in your house is in good shape. You said it is your "new" house, but is it new to you, or is it recently-built? At any rate, you should hold on the receipt and boxes until you test it!
