If everyone took the passwords off their wifi, we'd have a free, citywide wireless network. Sound like a good idea? Then help us make it happen!

Eyebeam's Open Cultures Research Group ran workshops in which participants were trained—in order for them to be able to train others—to open up a wifi network so that it is free, accessible, and secure for others while maintaining your bandwidth.  They also set up a web site to document the process and share the knowledge.
