Mac App that allows locking/unlocking and other actions based on proximity of iphone. There's a potential problem with bluetooth related battery drain on the iphone here, but if they've somehow cracked that, then this could be very interesting/useful – not so much for the security tools, but more for the fact that I could them script for proximity, and use that to log my location through the day.

About time. UK based locational services are about to get better. Or at least cheaper.
