I dunno how much FOV game-world integrates itself into ED game-world - but if the game-worlds are separate, I think it might be easier for FOV to just be sold as a stand-alone box, not requiring ED at all.
But FOV is also kind of an overhaul, technically speaking (according to the FAQ), so everyone benefits from it.
