Has any thought been given to system wide tagging of files?
Example, I've just been on holiday and I had music I played in the car going there and back, I took some pictures and I made a few movies. I'd like to be able to group these dispirate media types under one extended attribute, namely "holiday". Of course, next time I go on holiday I could tag them as "holiday_2", or even two seperate tags of "holiday" and "location."
