copy, move, derive come to mind quickly. Files do have a unique life cycle compared
to database content items.
I think my most recent thoughts on access control and the file API was
to leave that in the 'files as a node' layer. My current thought is that
files can exist in three worlds..
'files as an os level object' for people who want to do file handling as
it is now, and avoid the whole drupal thing, but gets you abstracted
'files as cms objects' drupal provides some hooks for lifecycle
management and deals with keeping the db data about files straight.
'files as nodes' The top layer of the files universe, provides the node
level interface to files, extensive access control, and all the crazy
stuff you can leverage node module for, because you want just an end
result from combining modules not to write a module. The
interactions/priorities of the three layers are still blurry to me in
some areas... access control is one of them.

I'd love to see more contrib file handling / API modules appear to
encourage some innovation and get peoples ideas into code. A good pool
of disparate ideas to juice up a, how dare I use the buzz phrase, 'best
of breed solution'.

If you have immediate needs go for it. If you have additional time on
your hands you've already found the file-api group :).
