It would be great if there was an API such as this. I was looking into doing a Google Maps mash-up a few years ago for UK schools, hospitals, shops etc. But decided against it because getting all the data would have been difficult and would probably have cost me a large sum of cash. So yes, I would certainly be interested in using such an an API. How would you expect people to contribute?
