See, that type of comment about the DM not allowing it is what I was talking about earlier. If you stack a VoP build up against a regular character and equip them with the proper amount of materials for their level, I'm not sure the VoP is all that unbalanced. Now, I understand that the VoP cannot be sundered, stolen, or someway otherwise seperated from the character like an item can. But is it really all that bad?
As a DM - I'd think that whole "Whew, no need to worry about exact treasure" thing because the characters will just give it all away would be kinda nice, too. Imagine how much easier it would be to be a party of 4 characters who all took the VoP.
This is, of course, just opinion and not stated fact. And I fully admit I could be wrong in my opinion. But my gut reaction doesn't feel like VoP characters are really all that off.
