Would it not be a good idea to do something like this for cd's and floppies?

I'm substituting FreeBSD for windows in some internet cafes.  Not automatically recovering from unmounted cd's, floppies and usbdev's, is probably the biggest PITA that I've found and haven't been able to solve cleanly.  I've had to put icons on the kde-desktop for accessing and removing them that many just ignore.  This is also the case in a corporate environment where I have had the same problem but they are a little better at using the
icon because it is their pc that crashes :)
