This makes no sense. I don't mind if they use their own sticks
on their own laptop. I do if they use it one this particular

Not necessary. Priveleges to do certain things are given
per user or to groups, it's done when a user's account is
set up and that's it. Sudo can handle this nicely. The fstab
entries for my own usb disks are there mainly because they
have dedicated mount points.
The last thing I want as an admin is a 'parallel administration'
such as polkit, in particular if it can grant priveleges just
by adding some files to a directory. That's very convenient for
package managers etc. but it surely does not enhance security.

Don't worry, there's no udisks on any machine I control. Nor Gnome
or KDE for that matter.
I do have polkit though, for just one reason: emacs -> gconf -> polkit.
So as my vim skills improve I'll probably get rid of emacs and gconf
