Open Source Data Entry Software for Mobiles

"EpiSurveyor is a free, open source tool enabling anyone to very easily create a handheld data entry form, collect data on a mobile device, and then transfer the data back to a desktop or laptop for analysis -- without expensive consultants, software subscriptions, or long-term contracts.

Coming soon: EpiSurveyor running on Windows Mobile, Symbian phones (and other Java-enabled devices)."

Potentially adaptable for agricultural field data capture?
