Virtual CDR driver

I am looking for a free or open-source virtual CD/DVD emulator to run in a Windows environment.

What I want is similar to what SlySoft's Virtual Clone Drive or Daemon Tools provides, but the emulated drive needs to be a burner of some type. The burner should be able to save disc images (.iso, .ccd, etc) to my harddrive - basically, the same as if I burned the files to a CD-R, and then ripped them back to a disc image.

I have already looked around some and come across 2 - DVD neXt COPY iTurns and NoteBurner M4P. Both of these programs create a virtual CD-RW drive, but they are integrated into their product (for burning from iTunes to create mp3 files) and cannot create disc images.

I am currently writing a piece of software that will have the capability to burn disc images onto CDs/DVDs, and I don't want to end up with a 100 coasters while I'm testing my software.

Anyone have any ideas?
