     You can also have a ramdisk partition for the user with the help
  of unionfs (or aufs) over the readonly "default parition". At each
  logout umount the unionfs, reformat the ramdisk and remount
  the unionfs (this is similar to your "deep freeze"). I think my
  earlier suggestion is cleaner. Neither necessitate a reboot.
