That's a very interesting article and explains why my unmounter is never 
called. And yes, it is the proper way. devd (and usbd specifically for usb 
devices) has been created to be able to propagate kernel hardware events to 
user land. It follows unix principles that root is owner of the machine and 
it's resources and decides what to do with it. Using these events one can 
call simple scripts or very complex programs.

As for KDE, also look at dcop. For instance:
dcop --all-users --all-sessions knotify default notify notify Me \
"I just sent you guys a notification. I could use it to tell you that the USB 
stick has been mounted." nosound nofile 2 0
