The promise of broadband haptics and sensory mapping.

while nokia focuses on the simple use of this technique as a substitute for ring tones it occurs to me that with a little tweaking quite a bit more information could be routed to our attention through the wasted biological bandwidth of human skin nerves. With some practice I think you could "listen" through such a patch. Just start out simultaneously feeding the audio stream to skin and ear then gradually lower the ear amplitude as the skin nerves are adapted to carry the audio path.
