Securing the Pyton Interpreter?

[Stephen VanDahm]

I'm looking for a way to install Python on a UNIX machine in a way such 
that any user on the system can use it, but only to execute scripts that 
are located in a certain directory.  I do not have root access on the
machine that will be running Python, so my options are limited.  I thought 
about hacking the Python interpreter itself so that it will examine the 
argument array and exit with an error if the script to be executed isn't 
in the appropriate directory, but this seems pretty risky.  The module 
'site.py' is imported automatically upon initialization -- I've thought of 
adding the check there instead.  I don't think either of these solutions 
are very elegant.  Is there a better way?

Thanks for your time,
