Yes, and apart from the fnf (I meet Isaac and Gordon a few weeks ago here in Spain), there is also the guifi.net project that is operating mainly in Spain. We currently have more then 22000 active nodes. The Model is the same: A parallel network with services, but also with exit nodes to the internet.
The project is currently working with the bmx6 project to create a new firmware called qmp which can be installed on any device that supports openwrt. The great thing about this mesh software is that it automatic. Once the antenna detects any other device, it will configure the connections etc automatically. It also auto detects any internet connection and announces it to the mesh. The system natively uses IPv6 for the mesh with IPv4 tunnels on top.
