I did. I put together a proof of concept using Google Docs, see

This uses OSM API and GMaps API − At first look, OSM does not return that great results, GMaps works better.

I was unsure of what to do with it (whether or not it was precise enough to mass-geoloc items)

To my understanding, Poulpy already did something along those lines − can you confirm ?
