The websocket support in QEMU allows you to connect with noVNC directly without using a websockify (proxy/bridge). You can still choose to connect to the regular VNC port using the proxy, but if you activate websockets then you can connect without it. The same is true now with libvncserver based VNC servers (e.g. x11vnc)
I am still waiting better support for Clipboard on QEMU. :/
Currently using NoVNC as a client. Works really well. Keyboard needs more love.
