title: Use of RFB or RDP for a single GUI application
body: <p>I’d like to be able to create a GUI that can be viewed over the network by a remote client.</p>
  
  <p>One approach is to code the whole GUI in HTML5 and run it from a server such as Apache; the main difficulty with this is that the GUI includes at least one, sometimes two, windows containing live video streams (without any sound) and there doesn’t seem to be a good way of streaming live video into HTML5 - especially as it really <em>needs</em> to be live; a few seconds’ latency would be unacceptable. </p>
  
  <p>Another approach (which I’ve done already, and actually works pretty well) is just to code the GUI as a desktop application (for example using Qt), and then to view the desktop remotely using VNC or Windows Remote Desktop. This gives the required responsiveness and lack-of-latency, but has the disadvantage that the whole OS desktop is accessible and not just my one application.</p>
  
  <p>So, here is my question: is there a mechanism or a framework available that would enable me to use RFB (i.e. the protocol underlying VNC) or RDP (that underlying Windows Remote Desktop) to provide remote access to a single GUI application rather than a whole desktop?</p>
