I don't know if anyone has tried it, nor do I know if it would work in 
the absence of water within the egg to transmit the sound waves.  
Another option not explored is ground penetrating radar.  However, my 
attempt last summer to locate dinosaur bones leads me to doubt the 
usefulness of the technique without major technological advances.  There 
is certainly a problem with resolution, which is presently too coarse 
for small embryonic bones.  Nevertheless, I would be interested in 
hearing of anyone playing with either techniques.
