Travelocity used to have a feature like this called 'dream maps,' but they dropped it - Presumably due to the huge computing requirements.
I used to mess around with Dream Maps but got frustrated that it'd show me a fare and a city, but then once you clicked through you frequently couldn't get that fare. It wasn't actually available.
I get the sense that they saved on the computing requirements by not actually running a live search when you launched the Dream Map. They'd just show the lowest valid tariff for your selected dates.
I'm pretty sure you could do your query in ITA....depart from Vancouver+300 miles and fly to a destination that was a string of airports (disabling airport changes) and then slot-rank the results on price. I used to have the string saved somewhere that was effectively all of North America. (About 25-30 airports, all +300 miles.) With $800 to spend, you could probably find similar strings out there for other parts of the world as well.
It was possible, but it was a bit of a pain.
