title: X11 screencasting multicasting solution
body: <p>I need to multicast an x11 application window to multiple (sai 100) clients in a lossy (wireless) environment.</p>
  
  <p>Right now, I was able to do it through screen grabbing (vlc) and h264 compression, but there should be a cleaner solution, something along the lines of a multicast NX session.</p>
  
  <p>Is there anything which could work with some glue, or should I build something for the purpose?</p>
