Foodzie is something I would definitely try if it existed in my area. It sounds like a combination of farmers' markets and the web. A great idea!

I also like the part about the producers making most of the money. Not only is that a classic cut-out-the-middleman play (in what seems like an inefficient market), it might lead to a whole bunch of interesting niche products becoming viable where they weren't before. Which, not to exaggerate too much, would make the world a better place.

I usually look at new apps from the perspective of a developer... can't remember the last time I got this excited as a customer.
