SiteFusion allows object-oriented PHP applications to operate as OS-native applications through a XULRunner-based thin client. The client connects to the SiteFusion daemon through an ordinary Web server, and applications run in separate continuous processes. Two-way communication is enabled, without the need for additional Web server configurations. The implementation of the XUL framework in a PHP class structure includes an implementation of the Mozilla tree view optimized for very large trees, supporting drag-and-drop, editable cells, and sorting.
exJello is a JavaMail provider that connects to a Microsoft Exchange server (actually, it uses the WebDAV interface exposed by Outlook Web Access). It is designed as a drop-in replacement for the standard POP3 and SMTP providers. This allows you to send and receive messages through your Exchange server in situations where a POP3/SMTP interface is not available (through a restrictive firewall, for example, or if your administrator simply does not provide a POP3 or SMTP gateway).
