I'd very much like to see something like the simple database functionality
of the BeOS filesystem. I'm on a severe typing diet, however, so I'm
unlikely to be able to do more than consult on the feature set and
implementation.

On BeOS, all files can have an arbitrary list of name/value pairs associated
with them. These attributes can be globally indexed or not.

Applications include:

- attach package information to files instead of maintaining a separate
database

- maintain version control information
- attach source URLS to files downloaded from the net so that you always
know where they came from (BeOS does this)

- cache editor state in file attributes instead of in separate files.

BeOS has a POSIX layer and Fred Fish has been porting GNU tools to BeOS, so
it's possible that GNU tar or cpio may have already been enhanced to support
these attributes.
