  • Tight encoding variant tuned for image-heavy applications, where ordinary VNC crawls
  • With VirtualGL it displays 3D applications remotely at interactive speed
  • Very light on resources, with a Java viewer that runs from any browser host
  • Simple, dependable remote control on a local network
  • VNC has no built-in encryption by default; you tunnel it over SSH or configure TLS
  • Setting up VirtualGL alongside it is genuinely involved
  • No relay service; you must reach the machine yourself over the network
  • VNC authentication is weak and needs to be tunnelled over SSH or a VPN
