It's worth pointing out the 'restriction' that this is using base data that is not accurate close to borders. Something we have highlighted before when using the simplified shape files as a base. But it is still a useful tool!
Quite a clever little hack to save memory, yes the shp file suffers from a lack of accuracy, but so does the geolocation input data. One reason I like the Gnome proposal to use spatialite to do proper geoprocesing is you can assign a buffer function to all borders and if you fall within the buffer then ask the user to make a choice, or try use some other heuristic to help decide.
