psyco is a JIT for x86. Jython and IronPython can take advantage of NET/Java JITters - IronPython is currently achieving better than CPython speeds on things (but it's unfinished so it may slow down when it actually has to run the complete testsuite). If you're interested in Python+VM you may like to look into PyPy which aims to do all kinds of interesting things. There will be new AST code in Py2.5 which should make manipulating them easier.
