Flightfox is a good idea (though I'll admit I'm unconvinced computers cannot reliably beat the crowd), but it needs work on implementation.
I tried it out and the winner quoted me an incorrect itinerary cost -- didn't notice that the airline's quoted price did not include airline fees and taxes (which are in the hundreds of $$ for international flights). In the end, the true winner beat skyscanner by less than the cost of the contest.
Honestly, I find skyscanner amazing; it is the only system I know that finds airline consolidators (well flightfox does of course too) - and has a very easy to use tweaking interface.
