NomeJS
Nome is a JavaScript library for location driven sites
...Nome gives direct access to location and weather data from an exposed JavaScript API allowing you to create context driven websites that deliver information relevant to your audience.
With clever thinking nome has the potential to change the way you deliver content to your audience. A bar could show offers for cool drinks if the temperature rose above 25°c; A shop could entice with targeted offers to customers right outside their door.
With nome giving access to more information than is currently offered from a standard browser session, you or your clients could be engaging customers in a new way.
