This is the MicroLink dLAN Audio device. It is able to stream music through electrical sockets at 192kbps quality. One end is plugged into a wall and connected to a PC via ethernet cable, the other end is plugged into a wall outlet and connected to speakers across the house for sexy streaming music. This is only available in the UK right now for 91.00 ($161.00) and uses the foreign style of power outlet. Any fancy electricians know if this will work on U.S. style outlets?
