How does it work? (Score 1)

So I'm just trying to figure this out - is this actually broadcasting a signal in a single area, or is the device using cell-network/GPS/whatever to figure out location? The idea of location-area tech has been around for a while. A lot of research has been done on this, like Cornell's Graffiti, ABTA, Intel, and somewherenear , but I haven't seen lot of practical application actually come out.

I ran across something new that does something like this that I have some hope for, called annotated earth. They appear to be in the initial stages still, but the way it works appears to be open (as in encouraging third party software - they seem to be the infrastructure and data for location-aware info). I especially like the Iraqi Weapons of mass destruction thing, good info to have if you're wandering around Iraqi, Hehe. Don't know if it's really going to work, still waiting on mobile devices that can use the technology they've done.

Anyway, I'll be interested in seeing how this goes.
