I know. We are not exactly rolling in cash, but this is the only thing holding us up right now. I don't think it would be too time consuming for someone to modify this enough that it will work--someone who knows what they are doing could probably knock this off in two or three hours.
I know the one major shortcoming is that the indexes are not updated in real time, but we were delta-indexing our vB forum every two minutes and nobody ever noticed. If I really wanted to go all out and learn this, I'd rewrite it to take advantage of the real time updating that Sphinx now offers. That is way more involved though.
Maybe I will ask Jake. I heard that he probably knows the answer.
