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.
