What SCSI-spec exactly. I have a list of (numeric) commands the writer
supports, and short verbal descriptions what they do, is this sufficient?

Hm, i'm not too deeply into programming, but just for curiosity, could you send
me that program, please? :)

Hm, i wonder if i have to take the machine single-user. Of course if that
swap-lag occurs that 1.2 has (and which stalls the machine for seconds with the
SCSI-led on), the CD to burn is hosed, but this would also appear in single
user mode, i guess.

On the other side, i see what a friend of me does under Linux with his burner,
and get more envious every thime he tells me about making his own CDROMS,
audio-CDs, even sampling audio-tapes and burning the tracks to audio-CDs.
He's using Xcd-roast... any chance to get this to work when we can transfer
images to CDs safely? I haven't looked into it yet...
