At the low level, with the current devices, I'm pretty sure you can
just write the data like a tape device. You just have to make sure
that you keep the buffers filled since it can't stop.
The main special software is to write a standard 9660 or Rock Ridge
formats. This has been solved by the mkisofs (I think that's the name),
which I associated with the Linux developers. I've used it on a Sun
to write a floppy and then mount it as a cdfs under Sunos.
Young Minds used to have the only (that I knew of) software that did
Rock Ridge.

a) Solaris will boot and use a 2048 byte block cdrom drive, I've seen it.
Not sure it works completely, but I did it with a standard Texel a couple
years ago. I was shocked that Suns still insisted on the special CDROM
drives...
b) Suns (and SGI's) until recently required a special CDrom drive
modified to return 4 512 blocks for each 2048 type normal block.
