Yes, sure.

I did, but only with CD-RW discs, which doesn't work well. It's known to work
better with DVD±RW.

No, why would I? The idea behind the above is to let _tar_ write to the device
directly, as it would do with tape devices. No fs involved. OTOH, if I wanted
a filesystem, that would be UDF, which I could still write to using the
method above (+ create the fs with cdrwtool before running pktsetup and then
mount it, of course).

And that would give me a multi volume backup if the data doesn't fit on one
disc?
