[pypy-dev] Sandboxing pypy

I have been following the pypy project for over a year. And I have been
playing around with it for some time.
The project I am working with Minimum Intrusion Grid : MiG (
http://sites.google.com/site/minimumintrusiongrid/) are looking into using
I would like to use it for sandboxing user code in MiG, more specific allow
the users to develop their own “scheduler” .
The MiG, it self is written in Python so we might even be able to run it on
pypy. But right now it is the sandboxing that I am working with.
For me it is a bit unclear in the documentation/website, but for that I read
into “An attacker that tries to escape the sandbox is stuck within a C
program that contains no external function calls at all except for writing
to stdout and reading from stdin.” means that I have to write functions that
emulates file read/write operations.
I have tried different things using the pypy_interact.py (just love the
–timeout parameter J), looked at code but have not been able to read files
or write files using the pypy_interact.py.
What have I missed?
