Neighbornode

Neighbornode is a captive portal on a residential Wi-Fi hotspot, containing a message board. It is designed to help neighbors who share an internet connection know each other better.{{cite web|archiveurl=https://web.archive.org/web/20090115000921/http://www.neighbornode.net/explanation.html|url=http://www.neighbornode.net/explanation.html|archivedate=15 January 2009|publisher=neighbornode.net|title=Neighbornode Explained}}

The message board can only be accessed within range of the hotspot. Individual Neighbornodes can be linked together to create a supernode, vaguely like Fidonet. It is implemented as an alternative firmware for the Linksys WRT54G router.
