NeroCMD vs. cdrecord Compatibility Issues

I’m trying to write multiple sessions to a CD-RW disc using both mkisofs + cdrecord on Solaris 8 and NeroCMD.exe on Windows Vista. As of yet, I have not figured out any options to allow the appending of sessions using each operating system/program. Has anyone had any experience with this? The following options are the closest I have come, but are still not working completely.

mkisofs -V session -o output.iso -r -J file.txt

AND

Nerocmd.exe --write --drivename d --real --iso test --import --close_session --use_rockridge file2.txt

Thanks,
Kevin
