The Neighbornode gives your home wireless network a job as the local welcome wagon. Its a great idea, particularly for high density areas. Here’s the pitch from the nodesters…

These nodes transmit signal for around 300 feet, so everyone within that range has access to the board and can read and post to it. This means that with a Neighbornode you can broadcast a message to roughly everyone whose apartment window is within 300 feet of yours (and has line of sight), and they can broadcast messages back to you. Boards are only accessible from computers that go through the local node.

Right now the nodes are set up to run off a Linksys wireless router. Can blind-node-dating by far behind ? More info at neighbornode.net/index.html
