Filesystem Abstraction

I have been thinking about a new project for Linux which is closely related to A New Gui. Its purpose is to provide a level of abstraction to the filesystem for use with user files in a new and easy to use manner. The idea is to provide a more user friendly way of accessing user files. This is not meant to replace the Linux filesystem, but to separate operating system and application files from user managed files. There hasn't been too much thought into the idea, but it may constitute a /var/spool article and possibly a new
project.
