An application like this exists on the OLPC XO written in python. I
think it's called 'Measure'. Rather than using reflected sound it uses
a second laptop to hear the sound and the clock sync is done via WiFi.
Differences aside, perhaps it will give you some ideas/code. At least
you know such a thing is possible with low fidelity speakers and
microphones :-)
