I don't see how having the CD burner software in userland makes that any different. I'm able to continue to work on my HPUX system while I'm burning CDs and it is all in userland. Even in the current setup it is userland process that is feeding the driver with the data you want to write. I don't see how having it create the SCSI command as well changes things that dramatically. Maybe I'm missing something here... Martin
