A team of grad students at UIUC have developed a way for people to securely share their bandwidth with their neighbors. Called Practical End-host collaborative Residential Multihoming (PERM), the device allows users to choose the best internet connection available among the current pool, and alerts the connection owners if there's any misuse with their bandwidth.
Would something like this catch on? Most homes are wary of wireless already, what with all the news about insecure wireless access points and neighbors stealing their bandwidth. Teaching these same people that oh, it's now okay for others to be using your connection because it's going to be monitored so your traffic gets priority? Good luck.
