I built everything myself from scratch in regards to the maps. This includes all vector paths (you wouldn't believe how much work this is), JQuery & Raphael interaction. There is also some websockets goodness. 90% of everything is handled in the background then pushed to browsers via websockets (for browser which support them).

To get location I do a variety of things mostly based off of the IP address of a user. However, I've built up a lot of meta data around locations which I may release later on down the road. Happy to talk more if you want to email me.
