I was a little curious if anyone else was doing Bluetooth Proximity Sensing.  There’s a few lifehacker things kicking around, but not much out there.


Are two companies that have given it a shot — albeit poorly.   I wonder if it will ever go main stream?  Or if Bluetooth level proximity is primarily just completely temporary until GPS is better.  (The two above companies are essentially just spamming via Bluetooth, so it’s pretty easy to see why they are not worthwhile)
