For demonstration of processes on the desktop it would be interesting to be able to either record or to stream via network a live video of the activities on the desktop. For both applications, the needed functions are provided by the software. For example, Homer can be used for recording a screencast or for presenting software processes via a live broadcast of the desktop picture. Like other video sources, the desktop picture can also be used during a video conference and therefore being showed to all participants for discussing in real-time. However, a non wished observation or control of the local desktop by a remote station are not possible.
