Create a VNC system with tclRFB (IBM developerWorks)
Suppose you have a graphical application running on a Linux box, and you've been instructed to port it to a Windows desktop or make it into a Web application. A nearly instantaneous answer is to feed the application display into a VNC server on the Linux host and rely on Windows- or Web-hosted VNC clients to view the application remotely. That achieves in an afternoon what might otherwise take weeks to port at the level of source code."
