That's right, but I just had one failure so far burning CDs while being
in multi-user. Just don't run any compute or i/o intensive tasks :-)

Right, works fine for me. AHA-2940, Dual P-100 (of which currently one
is idle :-), Panasonic CD-R-602 (sp?)

Yes, we have the sources for this, and no, linux-emul will most likely not work,
because it uses the raw-scsi-devices and some linux specific stuff. However,
someone posted a mail on cd-write-mailing list, that he had written a protable
scsi-lib which could probably be used to make cd-write (and the frontend
Xcd-roast) portable. I think the src for Xcd-roast and cdwrite are somewhere on There is a new alpha/beta version out on some host, but I forgot
on which.
