I'm sitting here with a Dell XPS 13 ultrabook laptop without a DVD device wanting to access the DVD drive on a MacBook Pro laptop. On the Mac you can choose to share access to the CD/DVD drive, but I have not found a way to access it from Ubuntu (12.04). Is it so that the Mac CD/DVD sharing function is usable only between Macs or is it possible to access the Mac DVD from a ubuntu system over the network?
