How do I allow through-the-web Controller Python Scripts to import
otherwise restricted modules? Plone4

I have a Controller Page Template and a Controller Python Script that
handles the action. It is great that I was able to add this form and
action script through-the-web so I do not have to buildout and restart the
Plone instance each time I make a slight change to the code. The problem
is that my python script is supposed to build a list of content objects as
an array and then share the objects with another server by POSTing the
JSON array as the REQUEST body sent to a remote server. I have my array
called arrayOfObjects that should look like "[{'param1':val1,
'param2':val2},{'param1':val3, 'param2':val4}]".
import json
...other stuff...
sJSON = json.dumps( arrayOfObjects )
The above code would work in a standard python interpreter, yet Plone
restricts the use of many modules for through-the-web Python scripts that
are managed in ZMI. That is a great security feature, however I want to
continue developing the script through-the-web and move it into filesystem
storage within my add-on product after it is all worked out. I have heard
that the allow_module feature of the AccessControl package should enable
the import, but it sounds as if you still might have to have it live on
the filesystem. Is there any way to have both through-the-web editing of
the Python Script and the JSON module that is critical to the
functionality that I am building? Thanks in advance for any information!
PS- The insufficient privileges screen is what I see when I import the
json module (expected behavior-not erroneous)
