The source license is absolutely clear that it is not allowed to link 
POV-Ray (or parts of it) to another program (linking referring to the 
programming meaning of having another program directly call functions 
from the POV-Ray code).  You are free to extend the existing means of 
POV-Ray to communicate with other programs though as long as these 
extensions don't contradict the intent of the license.

I don't know the programming language this is written in but it pretty 
much looks like this functionality (i.e. starting a render and 
displaying the results) is supported by existing communication means of 
all official POV-Ray versions.  And if you for some reason don't like 
the existing means of doing this you can modify them to better suit your 
needs (you could for example add a feature to have the render results 
sent via some network protocol *).

I didn't really understand the rest of your posting (the 'sandbox' stuff 
etc.) - it seems to me you are talking about limitations of the POV-Ray 
rendering engine and not about the License.

*) note this is neither a legal advise not an official statement of the 
POV-Team, just my personal interpretation based on the fact that this is 
already possible indirectly via operating system mechanisms or separate 
tools.
