Sounds cool.

This is the wrong place: KDirWatch is only for real files (local and mounted 
from remote e.g. via NFS).

You need to enhance the IO-Slave protocol for notifications: If an IO-Slave 
supports notifications, directory listings can last infinitely, and file 
changes/adding/removing are signaled while the listDir-Job is running. The 
only addition perhaps would be a signal "finished first listing", which would 
stop the spinning wheel in konqueror. But otherwise this addition should give 
no problem to existing KDE apps, as listDir-Jobs already can last quite long 
and files are given back in chunks.
