Yup. But we term our approach "CD-R/DVD-R" or "WORM", avoiding the term
"CD-RW/DVD-RW" in marketing and development terms.

We don't want to be accused of having a "Dieboldesque audit trail" and
that's what CD-RW/DVD-RW conjures up.

I disagree. When a later drive standard is available that reads and
writes the old media as well as new, the old drives tend to go away REAL
fast. When double-sided floppies came out, single sided went extinct
rapidly except in a few niches...the controller card for the Apple ][
series couldn't be switched to double-sided easily so they were a
holdout for a while...but everybody else?

And so on. Jeez, 720k floppies on PCs lasted only months before the
jump to the 1.44meg drives.

We WILL see the same thing with CD/DVD. Bet on it.

DVD burner drives at the "base size spec" of 4.7gig are not "early" at
this point...they've been retailing for over a year, price has dropped
from $450 for early ones to $100 range now...hardly bleeding edge. The
8.4gig spec IS a bit bleeding edge; the proposed 50gig-on-up
replacements extremely so (a few prototypes out there).

I'm arguing for DVD 4.7.
