That's easy. Simply redefine "mount" for floppies.
Like this: User logs in and calls mount(8) with -o removable.
-o removable means "this is a removable medium, the underlying fs is
activated on demand and the user is permitted to change the disk
whenever the light is off".
Note that /dev/fd0 remains mounted (with -o removable) over successive
disk changes, until the user logs out. This is how the association
between the user at the console and the *drive* is made known to the
kernel.
You don't sacrifice any multiuser features for this. It's exactly the
same as deciding who is using the mouse and/or keyboard. Policy remains
in userspace where it belongs.
