The RW and RO volumes share the same inodes (for the data part) as long as
they're on the same partition and the RW volume has not been altered since
releasing the volume. The space needed for the second volume header should be
neglegtable. That's as far as I know -- please correct me if I'm wrong.

yeah, but you were going to delete it anyways, weren't you? So the worst case
would be that the users mount the RW volume, delete the data and fill it up
with other data -- which they can not rely on since it will be deleted w/o
further notice a couple of days later. In this case you'll indeed end up with
twice the disk space used for a short period of time. I don't think that this
should be much of an issue in the days of Terabyte disks, shouldn't it? ;-)
