Address Book Continued is a multi-user address book Web application. It also makes use of AJAX, which means that page reloads only happen on login/logout; the rest of the operations is handled asynchronously in the background. It's well usable, even over slow connections. You can even install ABC on your desktop PC and configure it so that it doesn't require login for connections coming from the local computer.

Ryan's Electronic Diary Sheet (a.k.a. RyansEDS) is a Web-based Perl application which allows members of an organization (typically staff) to inform each other of their proposed whereabouts. It is designed to be a simple shared calendaring application which does not require complex (and often proprietary) client/server software. The diary sheet works on a week by week basis and stores its data accordingly. A shell script (batch file) is supplied that (when run as a scheduled event/cron job) will clear out data older that your chosen limit. Thus data storage is kept to a minimum. The diary sheet itself also has a feature that will prevent users from going too far forward or backward.
