This has been critically examined by several people and if the solution were this simple it would have been put in place a long time ago.  Charles Davis has spend over a year looking at how to implement CDROM functionality for MacOSX. 

So, here is my question:  How can the community be 100% certain that:

1.  The device has EXACTLY the same name on every available MacOSX installation?
2.  How can you be 100% certain that if the 'device' exists that the code will end up in CDROM_Verify()?
