OS X has had this capability built into the OS for a while -- you just mount .dmg (disk image) files and they can be treated as CDs.

"It is part of the calling of the ekklesia to learn to know the love of Christ that surpasses all knowledge and also to make known within the world of science 'the manifold wisdom of God' in order that the final end of theology, as of all things, may be that the name of the Lord is glorified. Theology and dogmatics, too, exist for the Lord's sake." — Herman Bavinck, Reformed Dogmatics, vol. 1, p. 46
