Feats that let you use Cha instead of Wis/Int for spell DCs?

There is a feat in the AEG Feats book called Fey Blood that makes your highest stat your casting stat. Though it does require 17 CHA to get, if you are playing a gish that is Sorcerer based, you can make STR your highest stat and you move from CHA based casting to STR based casting. Although, with the 17 CHA requirement, it virtually guarantees that CHA is going to be your casting stat, though I can see it being useful for rouges with high CHA or your party face.
