I don't think that is possible - how is one to distinguish your code 
from the code written by a user that calls one method in the restricted 
module?

What you _can_ do is to spawn an interpreter, and expose the allowed 
objects via Pyro.


The question is though: why cripple your users? If someone could reach 
an otherwise unreachable goal why do yoou hinder him? What is the 
reasoning behind that?
