I think the real challenge for Google would be to make it easy for the user. I have no doubt they could build some awesome filtering logic in the back. But I'm not sure they could put a super easy, non-engineer style front on it. But I agree they should try. And who knows? maybe they are working on that and want to get it rock solid before they open the flood gate. Build the filters before everyone screams "we need filters"
