This VPN connects to the wired Internet at only one point, but is composed of the landline Internet links from individuals' nodes. This central dumping point for traffic has a number of potential problems, all related to the tragedy of the commons. Money Administration Bandwidth Paying for a central link instantly means that we actually have to worry about billing, freeloading, recordkeeping, and all that jazz. This raises the bar quite a bit. I'm sure there are others who might have existing resources that are better-suited.
Security is an issue here.
In a Phase 1 network, individual nodes can attempt to make things somewhat more secure for themselves by allowing only particular MACs, particular SSIDs, or both. In a Phase 2 network, things are substantially the same, until we get to Option 3. Archives are available from the discussion, but only to list subscribers. Things to do One of the first things to do is to build a map, to see just how densely-populated we are and therefore whether the resulting cells are touching or widely separated. I'm thinking of a scanned-in version of the ubiquitous maps of Somerville handed out by the local city precincts, out to some radius around Davis Square.
