I created a similar project to share/track real-time location as you move, its an iPhone app that shares location and generates a url that can be opened by friends on any browser. It not just static location, but will show your real-time location, if you move, then the marker on url moves.

Check out http://shaloc.com use invite code "hackernews" to get iPhone app promo code to download. Give feedback, thanks.
