This is a reach.  

How (It's ftp)
When (exit points with access times, good idea, I may have
to add that to my FTP app)
Who (user profiles)  

I don't see how exit programs provide flexibility...
 unless you've got hooks in your programs to run processes
after certain commands are executed.

If everyone has *ALLOBJ, you can use FTP exit points to
control what users have access to using FTP and what FTP
commands they can use.  

When referring to FTP alone this does provide security.  

This doesn't mean you shouldn't have  good object security
in place, though.  It may be wrong to have a poor object
authority plan, but I'd say more do than don't.  :)

Now that's thinking outside the box to prove your point.

I repeat this again.  Why isn't IBM's FTP exit point
consistenet when it comes to reporting paths?  It resolves
most paths to qualified paths.. but not cannonical paths.
