Ask HN: Who here would be interested in a free daily updated GeoIP database?

I recently was playing around with Maxmind's free GeoIP database but was disappointed at how inaccurate the free version was.

I started hacking away yesterday at making an alternative database that seems to be more accurate, but it's still in the works. Who here would be interested in a free alternative, including and excluding cities, updated on a daily basis, and if so, which format's would you like to see?
