I live in a newer house, with sane wiring, and hpna rocks.

I have 3 rio receivers around the house using HPNA, and I also run lan connections to bedrooms and offices. I also have an Xbox in my living room and I use a tiny hpna bridge to hook it up to the internet.

HPNA is a great way to get a 10mbit connection in every room, easily. I have zero complaints.
