Currently running but in stasis, its technology is archived on Github. I am the lead system administrator for this project.
Commotion is a free, open-source communication tool that uses wireless devices to create decentralized mesh networks. It is a multi-stakeholder project with the dual purposes of making community network technology easier to use and more secure. I am the co-founder and lead developer on this project.
