The PyPy project, as I understand it, is to have a version of Python that's entirely written in Python. The RPython modules are the ones that will be compiled into C so that they can then be compiled into a virtual machine. I doubt very much if there's anything that can be done to subset it further. Their direction on performance is toward a JIT (Just In Time compiler), not to put lots of code in C so that it runs fast. The same goes for both Java and the CLR (IronPython). I believe there are plans to subset the JVM in the 2.7 release, but I have my doubts whether that will reduce the JVM footprint as far as running Jython is concerned. The intention is to reduce the initial footprint for runing the JVM under a browser. John Roth -- http://mail.python.org/mailman/listinfo/python-list
