Sorry - I knew that. I just didn't make the connection from one side of
my brain to another. Maybe "secure python" (spy)?
What made me think this would work are a couple of comments made here
and on the py3k list.
First, Armin (about a year ago, I think)made some comments about the
objectspace abstraction allowing a "Remote Object Space" and allowing
different object spaces to participate in the evaluation of code.
Second, comments on py3k list indicated that secure python is difficult
because of a) introspection, b) type inference, and c) GIL acquisition.
However, a) a partitioned object space would allow introspection to be
limited - go too far and you run into an opaque objectspace wall; b)
Pypy already has functionality to do some type inference - probably as
much as necessary; and c) Pypy doesn't have a GIL. The only relevant
GIL would be in the CPy host python, inaccessible to code in the Spy.
Of course, I also may be completely wrong :)
