A relatively new "Phase Change" technology.  Somewhat similar to MO, but
not quite - a rewritable purely optical.

`od' driver could be interesting as a start, but these things combine
a SCSI CD-ROM reader on one LUN, and a Removable Media on another
(not at the same time, though.)  

They seem to be an interesting backup media (slow at writing, but 4x
speed at reading) and should be capable of being bootable - even though
I did not manage to achieve that with ASUS built in NCR bios.

Since I have one, I will probably look into getting it to run under
FreeBSD.  Too bad I don't know much about SCSI programming.

BTW, one of these devices goes for ~400 USD, and media is 30 - 50 USD
(650 MB, formatted).
