PyPy with a smaller PVM for the full Python?

[Casey Hawthorne]

Currently PyPy is working toward compiling to C a restricted subset of
Python, called RPython.

Would it be possible for PyPy to "compile" the full subset of Python
by also using a lot smaller version of the PVM (Python Virtual
Machine) to go with the "compiled" code?
So, the user would be running the C object code and also a smaller
PVM!

Or would this completely remove or severely reduce any speed advantage
of the compiled code?


Similarly, for JPython (which is at Python 2.2?), could one also use a
lot smaller accompanying PVM with the JPython source code and JVM to
use Python 2.5 in its entirety?
