Open Source Farm Hardware
I have not had much time to dig into this site (sorry about the pun), but it looks very interesting. It’s a site dedicated to the development and sharing of open source farm tool and processes. For example, check out the open source tractor. Like the rest of the growing open source hardware community, it looks like they are using a mix of wikis, blogs, and other tools to distribute their work and share the results.
We should see if they would be interested in a more integrated approach along the lines of ODE.
