I wouldn't call using a few K's of memory a waste of resources. The 
program does of course not necessarily has to be started explicitly by 
the user. It would be added to whatever "autostart" mechanism the user 
interface in question would use.

Practically all desktop Linux distributions associates these kind of 
things with console ownership. If you're on the console, you are allowed 
access the graphics adapter, audio, floppy, cdrom, etc. devices. I don't 
see a problem with hotplug management following the same scheme. In fact 
, it _should_ follow the same scheme - wouldn't it be quite stupid if 
you could manage hot plug devices, but not access the floppy or cdrom?? 
Or does this concept have to change, too?
