NavXS, short for Navigation Exchange Service, allows people to build up a network of contacts just like MSN or Skype and keep track of them in real time. Instead of relying on instant messages or text messages, NavXS works by telling you exactly where your friends or contacts are in relation to your location.
In order to be tracked, you will need a Java-enabled phone or a PDA which all come with GPS nowadays. If you are at a really cool bar, you can bookmark it and the next time your friends are in the area, they will be able to find it just as easily as you can. Only your contacts can see where you are and you can turn off the service if you don’t want them to know. You can also download an application that will allow you to track your contacts from your desktop.
