Proximity lock using BT technology

Just read a great article on Engadget that has a nice application but gives way to some more ways to use this. It could perhaps be a cheap replacement of some RFID technology. We all now know the concept of flexible offices with activity based workspaces and how hard it is to find your peers:)

Well this could help you out here as well. This is the small post on Engadget and after the post I continue my comments

It may not be the ideal solution for those in need of some military-grade security, but those simply looking to keep their co-workers from snooping on their laptop may want to consider Phoenix's new Freeze application, which promises to turn any old Bluetooth-enabled cellphone into a proximity lock. What's more, you can apparently even use one phone to control multiple laptops, and configure the application to switch the laptop into a power-saving mode when the phone moves outside the proximity zone (which can also be configured to suit your needs). Best of all, the application is available as a free download right now (Windows XP and Vista only, unfortunately), and Phoenix seems to have some even grander plans for the future, with it now apparently busily courting computer manufactures in the hope of getting it offered as a standard option on new laptops.

If this also can set your communicator status to at least away and then when moving through the building keep tracking you (using the same proximity technology) people finally can find their peers again. Just look at the e-map of the office plan and you can see where the person's laptop is (and where the person is when he/she is not behind the laptop)
