iPod via electrical outlets--too late?

Way back before Wi-Fi, Bluetooth and other wireless technologies, some people touted electrical power lines as the next big thing for digital transmissions. But even though it was feasible, few companies marketed products that used the technology.

Despite this unknown potential, Pioneer Japan has gone ahead and released its "Music Tap" series of power-line products for the Japanese market, according to Newlaunches. The line doesn't include an actual media player but provides the equipment necessary to turn an iPod into a sound system connected by electrical outlets.

We applaud the effort, but it may be too late now that wireless audio systems are finally starting to become more common. Besides, with all the huge bricks that come with all our electronic devices, we don't have an outlet to spare.
