I came across this project today and wondered if the group is aware of it.
I found no reference in the mailing list archives.

It appears to be a very clever way of addressing any point (3m x 3m square)
on earth using a combination of 3 words.
For geo-location use cases where accessibility and the need for users to
remember their location are important this seems like an interesting
consideration.

Example: A user that is using a screen-reader that is doing a location
query is far more likely to want the what3words address read to them as the
result of their query as opposed to the lat/long corordinates.

The entire system can be embedded for offline use and is less than 10MB so
could easily be integrated into user agents either as a fully embedded
service or a proxy to the web service or a combination of the two.
