Richard,
would it be possible to adjust mix setting live via the webserver?
in particular keystone values.
could you display it with the same layout as the mix window but have say up/down left/right arrows of different sizes and a selection for which keystone point to control perhaps.

I would ideally like a way of remotely shifting a keystone point on a pixel by pixel basis. At the moment I use ARD and take a laptop on stage, but If I can alter mixes through the webserver then I could use an iphone or an ipad without the need to develop an app.
