Okay, because you asked nicely...
I've got a SPOT locator with me at all times. This little device pinpoints my location using GPS and sends it to the SPOT service through a global radio and satellite network when ever I press the "OK" button. So it works just about everywhere. I can even use this to send a distress signal when I'm in trouble.
The thing works like a charm, but the SPOT web service is a little weird. It forgets about waypoints after a short while. I still don't know why. A clever fellow has created SpotWalla to solve just that. It downloads the latest waypoints from the SPOT service and stores them. It even displays them on a nice map. here's mine.
What 7008000.eu does is just downloading the finished KML file from SpotWalla every now and then to display this little map. In this way waypoints can be combined with GPS photo locations and other nice stuff.
