tapping into finder events

[Randall Lee Reetz]

Just because apple has made this area of the event loop more protected doesnt mean it is lower level.  The user events we take for granted (mouse, keyboard, etc.) are lower in the event tree than are file tree events.  We get so used to the arbitrary structure of "what is" that reverence replaces rationality.

The suggestions posted to my questions have all required polling, which is peridic comparison of what was with what is now.  This is scary inefficient compared with getting delta messages as they occure.  Polling for deltas is the very definition of a system that doesn't scale.

It's MUCH lower-level than most of what Rev does - what makes you  
think it isn't? The fact that the OS-level tool for this has to be run  
as Root is a pretty big clue.
Read the caveat on http://www.kernelthread.com/software/fslogger/ for  
a bit more info.

The only application I can think of on a Mac that does anything even  
*similar* is AEMonitor which is only a developer tool and in any case  
is no longer under development.

Some of this could be done by setting up a series of hot folders and  
sending AppleScript messages to a Rev app. Not ideal, but just about  
doable, and much less of a security risk than setting it up from the  
Rev end.
