I am not the original poster, but  I could chip in to say what I would like 
in a similar vein. This applies to any type of file, including images.

 - adding notes associted with the files (without changing the files them 
selves)
 - adding tags
 - sorting /selecting by tags
 - processing tags either for a single directory or for a tree of 
directoreis.
 - being able to access this metadata programmatically in a language of 
your choice 

I am not a Mac type so I don't understand what "iPhoto for documents" is 
sugggesting.
