It's going to be more complex than that no matter what you do.
Re-sharing implies some kind of grant-of-rights, and may or may not
imply shared ownership of the file.  For example, if I
delete a file shared with me by somone else, does this just delete my shared
view, or the actual file?  If I'm the original creator of the file and
I delete it, does that delete all the shared ones too?  Or just my
view of it?  If I'm the creator of a file, and I unshare it, what
happens?
