Farmer's Market Technology: Urban Ubiquitous Agriculture

Pointer to a personal project of mine:

Farmers Market Technology: Urban Ubiquitous Agriculture. What happens when Malcolm McCullough's Networked Cities meet the world of urban agriculture? Ubifarm! I'll be gathering ideas and working on small open source projects to that end. Most of this is centered around small first steps like RSS feeds of available produce, SMS messages for the farmer's market, and when my soldering chops are down:pH and VOC sensor technology for the backyard garden.
