Geocoding that never phones home

Open the demo, open your browser's network tab, and type an address. You'll watch it resolve to a rooftop coordinate — 1600 Pennsylvania Ave lands on the actual building, within about ten metres — and then you'll notice what's missing from the network tab: a request carrying your address. There isn't one. The parser ran in the page. The gazetteer it resolved against is a file on a CDN that the page read a few kilobytes at a time. The query never left your machine.
That's the pitch, and it's worth being clear about why it's unusual, because the three things the rest of the market hands you each ask you to give something up.
