I'd suggest a search engine that tries to split information & money queries apart. The line would be blurry but I think the rewards would be worthwhile.
I also think a new venture should go local rather than 'the big win' of worldwide search. I can't put a number on it, but trying to spider the entirety of the web efficiently and in a timely manner is going to cost a lot in hardware & bandwidth.
