StringParser_BBCode is a PHP class that parses BBCodes with a real parser and not just regular expressions. This ensures that the HTML elements are correctly nested. It does not define any special codes, but allows the programmer to do so herself. It provides many features, such as the automatic detection and handling of paragraphs and the ability to apply different so-called parser functions to different portions of the text that is to be parsed.
The Mobile Web Proxy is a (CGI) tool to make more Web pages available from some mobile devices (cell phone Web browsers, etc.). It employs tag cleaning and paging so that Web pages it can access have far greater chances of being rendered on devices that cannot display overly large or complex pages. It is simple, but it seems to substantially extend the portion of the Web available from devices that otherwise display messages like "413: Page cannot be displayed."
mod_auth_openid is an authentication module for the Apache 2 Web server. It handles the functions of an OpenID consumer as specified in the OpenID 2.0 specification.

You can configure trusted/untrusted identity providers along with a number of other options.
CGILua is a tool for developing dynamic HTML pages and manipulating input data from forms. It uses the interpreted language Lua for codifying its scripts. It has been on the road for almost 8 years now, being used in many Web products and sites. It is extensible through Lua libraries and dynamic loading of C/C++ libraries. Scripts can be written as Lua programs or HTML templates (HTML with Lua code embedded). Scripts are platform-independent.
