Is there a way to set a funding goal without a sale? Maybe I'm just having trouble seeing the option, but I'd like to add a funding goal to a project with no minimum price - just to show customers they're participating in helping make the game possible in a more direct, visible way.

It's not something we support right now, sorry :(.

Would such a thing be possible in the future? I think it would be useful for things like "X will be developed when funding reaches this goal", or the like, especially for PWYW titles.
