It is a LE-only GATT profile. So any Bluetooth 4.0 certified hardware
should be able to run the Proximity and Find Me profiles. But I'm not
aware of any Bluetooth 4.0 hardware selling for general consumers (I
heard of a notebook with it sometime ago on this list).

For use cases, you should really take a look at the Bluetooth Low
Energy concept as a whole. See bluetooth.org for details.

The API is for the Proximity Monitor role. The Proximity Reporter role
will usually run on LE single mode (very low power, coin cell battery)
devices, but we will have a basic Proximity Reporter for testing
purposes as well, which could be later expanded to a full featured
Reporter.

For sure. This is just the D-Bus API, some graphical/console
application must be written to use it. We will provide test scripts
under the test/ directory.
