* Consumer and server support for extensions, including simple registration
* Yadis 1.0 and OpenID 1.0 service discovery, including server fallback
* Does not depend on underlying web framework
* Multiple storage implementations (Filesystem, SQL)
* Comprehensive test suite
* Example code to help you get started, including:
o WEBrick based consumer
o Ruby on rails based server
o OpenIDLoginGenerator for quickly creating a rails app that uses OpenID
