IBM recently started a new project on OpenNTF ( Lead Manager X ) The Lead Manager is a sample CRM application. It shows how to take an existing suite of Notes applications, and give them a new XPage based web front end. The existing rich client application (and the databases they reside in) are completely unchanged.

There is a video tour of the application on YouTube and an application overview on the Lotus Domino Designer Wiki.

Thanks to Jo Grant and Craig Wolpert for sharing the application and providing the full source code.
