DVD+RW media/drives are supposed to be able to do random per-sector
writing, so stick an ext2 filesystem on it, and in theory you should be
able to do so. DVD-RW media/drives are supposed to do per-sector
/re/writing, so should be possible there too.

After that, you're back to the media durability issue though. Optical RW
media has a limited number of writes that can be done.
