Satisfying our craving for a device that allows users to share music wirelessly to anyone within 30 feet or so, Aerielle's i2i
Stream improves on the existing Engadget ghettoblaster
by limiting exposure to only headphone wearers who choose to listen in. Broadcasting on the already-crowded 2.4GHz frequency, it promises one-to-hundreds broadcasts, with as many as three channels broadcast in the same location without interference. For $129.95 you and a friend can share an iPod, stereo or any other audio source without catching a sound pollution charge for up to 7 hours, or for $69.95 get just one and wait for another user to walk by. Should be on sale any minute now.
