Sorry for bumping an old thread, but I did think of one more potential use of the tracking technology. Say your out looking for a laptop and your in JB HiFi chatting to the rep while Harvey Norman send you a message (spotting your in the oppositions shop) that they will beat any price offered to you by 5%. It would require real time tracking, but could be fully automated to show whatever there current deals are.
