The Book of Exalted Deeds and the Book of Vile Darkness are for mature audiences, not because of naughty bits, but because of things like the VoP.
These are books that should be kept far away from rules lawyers. Vow of Poverty, for example, is not meant to be picked apart in usual rules debates. It's meant to compensate aesetic characters for class features that they would lose for giving up their material possessions. No character class or prestige class should be rendered impotent by taking the Vow. The material is "mature audiences only" because you have to maturely handle the adjudication of the Vow, for example, and what it means for a given character.
I believe the sage stated in one Dragon Magazine issue that a Samurai would have to give up his ancestral daisho with the Vow of Poverty. I completely and wholeheartedly disagree. In addition, I think the Sage should avoid the Book of Exalted Deeds and Book of Vile Darkness if his adjudications are going to be from a rules lawyer standpoint. A Samurai with the Vow of Poverty should have the Vow tweaked to accomodate the daisho. Why? because that daisho is part of who he is. He loses honor by losing/giving up his daisho.
