red5-screenshare - Java Webstart application that can be run from a web site without installing any desktop software and will publish your desktop screen as an RTMP video stream to a Red5 server using a standalone RTMP client and the Screen Video Codec.
It also includes a Flex viewer application which can be used to remotely control the desktop. Double click the desktop screen and follow the shadow mouse pointer. You should see two mouse pointers, your real one and the remote one lagging behind. This application is based on the source code for the open-meetings desktop publisher, but converts the screen frames into a RTMP video stream on the client at source. It uses the Flazr library.
