Virtual Device

Hello,

I'm looking for a way to create a virtual drive that is fully compatible to a common dvd/cd-writer. The idea is to offer the user the ability to take advantage of the Finders and other applications built in burn ability without the presence of a physically connected dvd/cd-writer.

Basicly disk images are exactly what I need with the exception that usual disk images can not be used as burn device. Because I'm not very familiar with OS X driver development, I'm not sure what would be the best way to do that.

One idea is to modify the I/O Kit registry of an existing disk image to match the required filter criteria to make the image available as burn device. Is that possible at all?

The second idea is to create a custom driver (KEXT) for a virtual drive (ATA/SCSI/Firewire or USB) to emulate a real DVD/CD-Writer device. If so, on what level do I need to emulate the device?

Or maybe there is an easier way to make a virtual drive available as burn device?
