WORM, sold!

I don't think you're wrong, I just think that there is development risk
and additional cost in not starting with a CD.

>From where I sit :
(1) The DVD spec is not stable, There currently two competing DVD write
spec's out there (DVD-W & DVD+W). Extensions like DVD-Audio are still
(2) There continues to be a premium on the software / hardware side for
software that supports DVD.
(3) Knoppix / Live-CD / OpenBSD CD are, well, CDs. So It's either really
hard or negligably transparent to move to DVDs.

I agree it is the right thing to strawman a DVD+WORM deployed platform.
Are you betting on DVD-W or DVD+W ?

I just don't see the traction that DVD vs. CD has on the other aspects
of the project.

So 720KB floppies, I've been trying to remember the capacity of my 8"
Floppy drive I have in the garage. Do you know ?
