I don't see any concrete example.  Note currently communication of 
POV-Ray via stdin and stdout is essentially one-way - the only input it 
recognizes is to pause after the render when pause is on and wait for a 
keypress.  But this can be changed of course.

In a lot of cases these techniques are simply abused, often simply to 
obfuscate the communication (so 3rd parties have difficulties to develop 
replacements for one side of the communication, often made waterproof by 
using patented techniques in the communication).  But again a concrete 
example would be necessary.
