The general technique goes something like this.
mkisofs -various-isooptions stuffwantingburning | cdrecord -cdroptions
The main problem is not being able to produce the data fast enough which
may or may not be a problem. Experiment with dvd+-rw media and any
buffer size type options to mkisofs/cdrecord.
Using a named pipe to do compression/tarring might go something like
mknod spout p
tar czf spout mydata &
gzip -c compressable-data >spout &
(bzip2 very likely too slow)
mkisofs -various-isooptions spout | cdrecord -cdroptions
I have a suspicion mkisofs will look at the pipe and decide it's a zero
You could always write the thing in a format other than ISO.
