There are a number of fantasy stories, where a villain cast a curse or other spell that can only be removed in the event of the casters demise. There's currently no mechanic to allow this in D&D, so I thought would make one. 
Let me know what you think.
So Long As I Live [General]
You may tie the effects of your spells to your life force, they can only be destroyed by your death.
Prereqs: Caster Level 15th
Effect: Any spell with a duration of "permanent" can be made to last as long as the casters life. The spell cannot be removed by any means for as long as the caster is alive. When the spell is successfully cast, the caster may spend an amount of XP equal to 1000 per spell level (or 500 for a cantrip). All dispel checks on the effect automatically fail, as does antimagic and disjunction. If at any time the caster is no longer alive, all spells effected in this manner are automatically dispelled.
Note: Undead creatures are unable to use this feat.
Note: Should the caster come back to life, the spell is not restored, if he wishes to renistate the spell effect it must be cast and XP sacrificed again.
Note: This feat can be combined with the permanency spell, all XP costs stack.
Note: Divinations such as Commune and Contact Other Plane are capable of exposing the identity of the caster of such a spell, and a Legend Lore or Vision spell automatically exposes the casters identiy.
