The third movement, which I'm listening to now, is quite beautiful and serene, with hushed voices singing over a gentle tympani pulse.
However, it's also important to realise that it's not a panacaea. John Viega describes the way in which open-source does not cure security problems, and can even exacerbate them (because they're more readily found) in this interesting article and Eric Raymond (again) describes a similar issue with respect to the Quake 1 game.
Not that I lap up everything Raymond writes. He has an essay on the right to bear arms that I find completely astounding.
