The potential of the programmable pipeline

[VIRGIN KLM]

I'd be fine with something that automitically applies bump mapping and displacement mapping (not a post processing effect but real ones). I bet you can do it and it's going to work nicely on alot of games. You could generate the maps using the scalled textures and applying effects to them. It won't look as good or as acurate as real maps but it shouldn't be far from how a real map would look.
