As others have said, DVD media is not an appropriate choice for this
task. Basically, you are talking about using a session oriented
physical media and trying to turn it into a character or read-only block
device. In theory, you should be able to do this with a DVD-RAM device,
but that would still allow writes and you would need to protect it with
software somehow, which really leaves you back to a separate OS running
that access. Perhaps you could use Xen to run a logging host against
something like DVD-RAM.
My low-tech, quick and dirty approach for a single machine would be to
just use a write-only media (from the PC's perspective). Although
noisy, you can't top a dot-matrix printer with a fresh ribbon and a case
of that continuous paper. It's good for REALLY important servers with
low data access volumes as well.
My personal preference would be to take something like a Linksys
WRT54G(L), install a 2GB SD card in it, and use that for the remote
syslog server. Cheep device, low power, and most of us need some form
of a border router anyhow. Plus, when you eventually add more devices,
you have a real logging system in place.
