Organization structure

The mesh organization will be a 501(c)3 but will not own the mesh routers. The mesh hardware will be owned by the community that makes up the mesh.

Exit nodes

The exit nodes will be owned by the 501(c)3.

With regards to running exit nodes, Noisebridge, another 501(c)3, already runs a Tor exit node which should be legally similar to a mesh exit node.
