There is another aspect.
Privacy.
For example, I might be happy to be visible to other phone users in 
50-100m, and my friends.
I certainly do not want to be locatable by a random person over the 
internet.

This does imply some sort of server, to which I upload my position, and 
will push to me information about any nearby phones.

Also that publishes public key encrypted position, which anyone can 
download.

A static database simply can't really do this.
