Reminds me of an old project I did where I built a fuse system for this, files still lived on a normal ext3 fs, but the overlay presented files as tag paths, yo you could access, for instance, a movie like /tagfs/movies/year/1999/matrix.avi or /tagfs/movies/genre/scifi/matrix.avi There was a special path /tagfs/untagged/ which listed any files that didn't have at least one tag.
