Note that creating virtual CD-ROM drives attached by SCSI and then loading them with virtual game CDs so that said game will play, was the entire basis of the drive emulator market for a while. :-) I have also known people who use this technique to create an encrypted disk image which is distributed with their program which provides the 'secret bits'. Sort of like mount the image, decrypt it by giving it the key, and then launch the app which loads its .dll files from the newly decrypted attached disk. A bit of obfuscation which minimizes the impact on the application that you're trying to keep out of the hands of people without a license to it.
