If somebody is truly interested in audio coding of Linked Addresses, I 
could perhaps lend a little bit of assistance. But since that stuff goes 
well into the DSP department and I'm somebody who you'd steer well off 
in your critical path, interested folks should contact me privately and 
not expect too much.

(Quite a lot of data can be put into audible frequencies. It's the 
practical and protocol issues like coding, error correction, framing, 
synch, expected propagation conditions and so on which make the problem 
convoluted. With a reasonable design, a typical room and two consumer 
grade mobile phones at no more than 1m apart from each other, I see no 
reason why 1200-4800bps one-way contacts couldn't routinely be achieved 
at .5-.1.0 second latency or so. Might require some asking around, 
though, since I'm only privy to the theory and not the practice.)
