While reading a weekly edition of LWN: Kernel development, I think the article relating to the future of file system is quite interesting and may warrent looking into one of the related project. Still not completely sure of the benefits completely, but I believe it is to allow for better file interaction. I think the concept is basically adding an additional layer of meta data linked with each file. This almost seems like the idea of resource forks found in Mac file system, or to a degree the ideas brought forth in the Amiga DE interpretation of a new idea instead of working with files. I'll have to find that reference at some point.
