Marantz WEAVE: Stream Music Through Your Electrical SystemS

Similar in theory to the MicroLink dLAN, the Marantz WEAVE lets you stream music through your electrical system to any room in your house, provided that room contains a WEAVE receptor.

Up to six ZC4001 receptors can be plugged in your home at once to receive audio, but to transmit audio you'll have to get a ZR6001 WEAVE amplifier or "receiver". The transmitting "receiver"—slightly confusing terminology, we know—and one ZC4001 "receptor" will run you £700 ($1,289) together, and extra ZC4001 receptors cost £200 ($368).

This is only available in the UK as of now.
