A recent news story
claims that (in the U.S.) DVD-Rs cost about $10, and rewritable ones
about $5 more. I haven't tried hard to verify either number, but a
30-second search of one Web site found one brand of rewritable DVD at
US$19. Not cheap, compared to CD-R, but I can certainly afford a few
for level 0 dumps. And as you point out, most level 1 and higher dumps
won't take up more than one CD-R.

Yes, I can write a script that uses pipes, and I probably will (I
hadn't realized that piping dump | mkisofs | cdrecord would work). But
I'd prefer a solution that let me use dump/restore's volume-switching
