Bluetooth is great fun! You have a couple of options to look at with this one, Bemused
is a cool option, you can use a Bluetooth phone as a LIRC
remote. You could use something like bluemote
too. Start getting stuck into them, if you know Python then it's easy to use pybluez
to chuck together something a little more specific to your needs, decent Bluetooth frameworks exist for most languages as well.
That's a bit to get you started, post back if you need anything else
P.S. Open SUSE 10 & KDE 3.5 rock!
We don't care.
