The product isn’t exactly new, but I just got in Netgear’s Powerline AV Ethernet adapter kit, which promises ethernet connection of up to 200Mbps over your home’s powerlines. From early indications, it works a treat, but it does have one major design flaw: 
As you can see, you can’t actually plug it in next to any other device, as it blocks the better part of two plugs on a standard wall socket.
Even having the plug stick out another 5cm so the adapter sits over another powerplug would fix the problem. Fortunately, it seems to work through an extension cord, although I’m certain that would have some kind of effect on performance. I’ll let you know how the product performs once I’ve played with it a bit more.

One gotcha is if you have separate circuits for power outlets in the house. I have one that will work in about half the house but not the rest because there is no physical connection between the power lines. It won’t bridge across different circuit breakers in your power box.

Saturday, May 2, 2009 at 9:49 PMIt seems to me this could be easily rectified by:
1: Making the plug taller, rather than wider.
2: Adding a power socket on the back of the device, so it can be connected inline with another device (to accomodate single powerpoints).

Saturday, May 2, 2009 at 11:36 PMI have the same problem, I used an extension cord with a pass-through type plug, it gives the box an extra 25mm extension from the wall socket.
Why they dont make big plugpacks offset to the left or right so they dont crowd a 2 socket outlet?
