Ok, maybe not all of it yet, but I do have a use case right
now for being able to dynamically switch between the normal
"both" mode and "output"-only mode.  In the Form Model GUI
I want to default to showing the widget definitions with an
easy-on-the-eyes read-only summary, and for each widget
definition have a button/checkbox/tab/whatever to switch
just the selected widget definition(s) to collections of
editable input widgets like the sample has now.

We could solve this several ways:
* Make the both|output|etc. setting dynamically settable as
  suggested above.
* Introduce "alias" widgets to hold configuration, while
  referencing other widgets for the data, and then wrap
  alternate "both" and "output" alias widgets in a "choice"
  widget to control what is sent to the view layer.
* (Hacky) Have the view layer contain a hidden input for
  these output widgets so that readFromRequest does not
  reset these output-styled field widgets to null.
* (Non-portable, but sometimes a good option) Only use
  client-side tools (js/xul/etc.) to switch between modes.

WDYT
