As an aside, you know you can already do this via a Google API right? That is, you can find a GPS location for an address or approximate address (city & postal code will do). Usually, if the address is not specific, the nearest road intersection GPS is given or indeed 4 GPS points that denotes the bounding box encircling the area. The country is not needed unless the city and postal code combination is ambiguous... so safer to add. You can do the reverse too, supply a GPS and obtain an address or approximate address where ambiguous. As long as you hit less than 1,000 requests per day, the service is free. Results are returned usually in under 2 seconds in nice full XML or JSON. Here's an example using my postal detail - one XML and one JSON: https://maps.googleapis.com/maps/api/geocode/xml?address=Midrand+1684+South+Africa&language=en https://maps.googleapis.com/maps/api/geocode/json?address=Midrand+1684+South+Africa&language=en (Might be less effort for you to just piggy-back off this until your system becomes very adopted).
