People who *are* security experts have looked into modifying Python to
make it secure, and given up on the project as unrealistic. Generally,
taking an existing project that wasn't designed with security in mind
and making it secure is hard. Not impossible, but not easy.
You might consider using Jython and jythonc to produce objects to run
in the JVM. Not only was that designed with security in mind, but most
browsers come with a JVM already installed.
