Hi,

As far as i know, it is only possible to protect your doc as a whole; for 
this you can use acrobat (open doc, save with security options).

The following demo show that you can misuse the form mechanism to get non 
selectable data, but since the content is an xform object no interactive 
features can be applied. I can i,magine that with some trickery (no time 
right now to test it) one can hook this into the page builder (using 
background/foreground feature) and so handle pages.

\setupinteraction[state=start]

\starttext

\definesymbol
   [test]
   [{\framed[width=10cm,aligh=normal]{\input tufte \endgraf}}]

\setupfield[test][option={readonly,unavailable}]

\definefield[test][check][test][test,test]

\fitfield[test]

\stoptext

I cc this to the context list, maybe someone knows more.
