The available columns are
Postcode, IntroductionDate, GridRefEast, GridRefNorth, County, District, Ward, UserType, GridStatus, Country, WardStatus, NHS_Code, NHS_Region, Long, Lat, OSRef, Update
You can already get the co-ordinates from a postcode using google maps. So I can't think of anything massively exciting you could do with this information. Maybe some sort of offline navigation app.
