Quickly gathering your wits, you penned down the following quick requirements:
1. Each customer who comes to your site needs to be able to find the closest kiosk to his or her current location.
2. He or she might also want to know the closest kiosk to any location.
3. You want to let the users determine the radius of the search.
4. Finding the locations of the closest kiosks, you need to show him how to reach them.
5. You have 500 kiosks now, (and you need to show where they are) but another 500 will be coming, in 10s and 20s, so the location of the kiosks need to be specified during the entry of the kiosks. You want to put all of these on some kind of map.
Sounds difficult? Only if you didn't know about web mashups!
