You could possibly do something with the TI Chronos watch. The dev kit is reasonably priced, especially when they do their periodic deals. I got mine, including shipping to the UK, for $25.

Seeing as I don't always take my phone when I leave my desk I was wondering whether there were any other devices that could be used for this, something small that could be left in a pocket or on a belt loop. Ideally it would be a class 3 or 2 to keep the range short. What software is good for this for OS X and Linux?
