I wanna suggest you to keep in consideration both ReactOS (the open source Windows NT clone) and Haiku (open BeOS clone) as target OSes for your software:
www.reactos.org
www.haiku-os.org
I also suggest to keep in touch with Infra Recorder (a really interesting GPL burning software) author: infrarecorder.sf.net
Marco Ravich.
CDRBQ has a new trick. Now you can use CDRBQ to burn CDs from cue/bin files with cdrdao.
This release is just one more step in the right direction. I want to make this the most complete cd burning utility for linux, but without making it too complex.
Enjoy!
Brad.
