On a largely unrelated note, except that it also involves magic items, has anyone else noticed that most of the limits that the epic magic item creation feats allow you to exceed don't actually seem to exist in the rules?

I've been going through the SRD and as far as I can tell there's no limit on enhancement bonuses to ability scores, no limit to weapon mods as long as they aren't enhancement bonuses, and the intelligent item rules explicitly allow items to cost more than 200000 gp (one of the item special purpose abilities ("Item can use true resurrection on wielder, once per month") costs 200000 gp by itself and necessarily goes on an item that already has significant other abilities). The only one that seems to actually exist is the limit on weapon plusses.

So if you take an epic item creation feat (other than craft epic arms and armor) you're basically buying a 10x markup on everything you make
