In "Visionary in Residence: Stories" (Bruce Sterling), there are different short stories. In one of them, there is this email discussion about the design of a new category of product based on location-based technology:

If Al has the location and condition of all his possessions cybernetically tracked and tagged in real time, maybe Al is freed from worrying about all his stuff. Why should Al fret about his possessions any more? We've made them permanently safe. Why shouldn't Al loan the lawnmower to his neighbor? The neighbor can't lose the lawnmower, he can't sell it, because Al's embedded MEMS monitors just won't allow that behavior. (continued)

So now Al can be far more generous to his neighbor. Instead of being miserly and geeky "labeling everything he possesses," obsessed with privacy--Al turns out to be an open-handed, open-hearted, very popular guy. He doesn't even need locks on his doors! Everything Al has is automatically theft-proof--thanks to us. He has big house parties, fearlessly showing off his home and his possessions. Everything that was once a personal burden to Al becomes a benefit to the neighborhood community. What was once Al's weakness and anxiety is now a source of emotional strength and community esteem

Why do I blog this? because the excerpt describes a relevant possible consequences of location-based services that has not been explored so far in what I've read concerning their usage.
