It doesn't yet support "live programming" like this, but the hope is the framework would eventually be used to easily make these sorts of things.
So far, the focus has mostly been on the user input side. There is a constraint-based system for defining input values from different "devices", i.e. keyboard, mouse, gamepad, head mounted display motion tracking, arm motion tracking, etc. There is even a rudimentary gesture system, where things like a nodding gesture or head shaking gesture can be wired up and used to activate commands just as easily as a mouse click or key press.
The framework also supports multi-user environments, and I've already started building the text input controls (somewhat similar to what is shown here) to do things like this (right now, it's only useful for live chat). Eventually, I'll have buttons and text boxes and togglers, etc.
If you're interested in this sort of stuff, please consider joining me.
