Well not this article but interesting.

Sound Waves Levitate and Move Objects http://rss.sciam.com/~r/ScientificAmerican-Global/~3/WhVxLcNGF8o/article.cfm

A new approach to contact-free manipulation could be used to combine lab samples--and prevent contamination:

Water droplets, coffee granules, fragments of polystyrene and even a toothpick are among the items that have been flying around in a Swiss laboratory lately — all of them kept in the air by sound waves. The device that achieves this acoustic levitation is the first to be capable of handling several objects simultaneously. It is described today in the Proceedings of the National Academy of Sciences.

There is actually research that was done dealing with Teleportation of molecule/Atom from point 'A' too point 'B' and the sciences behind it have confirmed this is possible, but with very minuscule Mass/Weight objects. It is cool though.

Won't be too much longer in Cosmic time before the Human Specie's can take a trip from NY to LA and it will be an instantaneous event!! JK, probably is a ways from being commercially viable.

The essence of levitation technology is the countervailing of gravity. It is known that an ultrasound standing wave is capable of suspending small particles at its sound pressure nodes and, so far, this method has been used to levitate lightweight particles, small creatures, and water droplets.
The acoustic axis of the ultrasound beam in these previous studies was parallel to the gravitational force, and the levitated objects were manipulated along the fixed axis (i.e. one-dimensionally) by controlling the phases or frequencies of bolted Langevin-type transducers. In the present study, we considered extended acoustic manipulation whereby millimetre-sized particles were levitated and moved three-dimensionally by localised ultrasonic standing waves, which were generated by ultrasonic phased arrays. Our manipulation system has two original features. One is the direction of the ultrasound beam, which is arbitrary because the force acting toward its centre is also utilised. The other is the manipulation principle by which a localised standing wave is generated at an arbitrary position and moved three-dimensionally by opposed and ultrasonic phased arrays. We experimentally confirmed that various materials could be manipulated by our proposed method.


So if you had big enough speakers, could you literally move mountains? Or build pyramids? Or coral castles?
