Found this on Edd Dumbill's blog, sounded not only interesting but actually useful. May consider buying his book if its things like BlueFOAF, will have to look out for packages so I can also use the Bluetooth enabled GNOME.
Can wait to try out these things with my newly installed GNU/Linux. Yes thats right I did finally install Linux on my spare box without anyones help. Got GNOME and KDE installed plus loads of default packages which I dont need but then again its all there for future use.
