Jonas Salling, the guy who first released software to let your Ericssony phone talk to your Mac via Bluetooth, has done it again, with Sony Ericsson Clicker. Not only does this allow you to control your Mac from your mobile, it also allows the triggering of AppleScripts based on proximity.
Right now, when I walk away from my Mac (with my phone), iTunes pauses. When I return, it starts up again. This is… er… kinda cool. It’s really not a million miles away from some of the stuff AT&T Labs Europe were doing with RF tags back in the mid-90s, moving peoples’ desktops around the building as they sat in front of different workstations.
Only, unlike RF tags, most people actually do carry mobile phones.
