I was curious about the new powerline adapters that are rated at 500. Right now I am using wireless N for my htpc. If I need more bandwidth I would either run a cat6 wire or use the powerline adapters. My wired connection via my 1gig router copies files to my nas server at HD speeds. I was lucky to buy 4 3Tbit drives for $109 last month. Now the same drives are $259 due to the flooding in Taiwan.
