The WendzelNNTPd is a IPv6-ready NNTP usenet-server with the main goal to be as easy to use as possible. It is portable (Linux/*BSD/*nix), supports AUTHINFO authentication, contains ACL as well as role based ACL and supports invisible newsgroups. It currently supports MySQL and SQLite backends.
PepperSpot is a captive portal or wireless LAN access point controller which support the IPv6 protocol. It supports web based login and it supports Wireless Protected Access (WPA). Authentication is handled by your favorite radius server (over IPv4/IPv6)
Slightly Automated Public Turing test. CAPTCHA like authentication but 'Slightly' because you have to add the pictures yourself, and 'Automated' cause they are randomly changed.
