Camera mirror over RealVNC

One of the first things I did when I got the Pi configured was connect to it over RealVNC and try to fire up the camera. The built-in raspistill utility will not be mirrored over RealVNC, since it renders directly to GPU. However the QV4L2 utility will work fine, it will render video from the Pi Cam...

Re: Proposed Client -> Rasp Pi Control Software

How feasible would it be to run a web server on the Pi, with an embedded video stream, and buttons for driving?

Then no client is required, just go to the IP address of the robot.
