It works, using shunt/flyisofs. I will be making offsite backups much much
more than I will be restoring them, and this is fairly easy:
shunt -c 'dump -0af - /path/to/backups' +
'flyisofs mbc=2295104 fbc=2000000 |
growisofs -Z /dev/rcd0c=/dev/fd/0'
The shunt program prompts to start the dump, and also prompts to start
flyisofs, so one must depress ENTER twice after entering this rather long
command. Note that mbc = media sectors. DVD+RW uses 2,295,104 2048-byte
sectors. Note also that fbc is under 4GB, to avoid any ISO9660 problems.
The flyisofs program will close when the ISO is full, and shunt will prompt
me to restart it, so I have time to change media and press ENTER again.

I have looked. 2.4.5 is really for tape only. 2.5.0 has not been ported,
and its introduction mentions optical, but ... it is the same as 2.4.5; you
must write backups to hard drive in CD or DVD sizes, and then burn them
manually.

I've started, I should have it done this evening, and will post it on ports@
when I think it's ready.
