I’m doing a bit of Shameless promoting now 
Sabre is a plugin for the AmaroK music player (it’s a KDE application, but I still use it anyway), which will ping a Bluetooth Device (I use my mobile phone for this). If the device moves out of range, it will pause your music, and invoke the screensaver.
Currently it is in the early stages, but we are working on support for KDE distributions right now (currently works for Gnome only, though it is a key feature for v1.5). Feel free to download it from here, and report any bugs etc. here.
I hope you enjoy it!
