My humble advice for this slide deck is: get to the demo. In this case, it's phonetically encoded coordinates. It's a cool idea, but requires adoption of a "majors system" like system for converting numbers into sounds. That's asking a lot!
The idea is to use what we already have now, "Names" but encoding information inside them, if you get to the Location Aware Street Names slides, you can see how it can be used to make some very interesting stuff, fast forward to slide 55.
Just my 2 cents.
