You might also want to add numexpr and numba to that list. Numba might
actually be quite close to pymothoa (hadn't heard of it before).

Personally, I like the idea of having a JIT compiler more or less as an
extension module at hand. Sort-of like a co-processor, just in software.
Lets you run your code either interpreter or JITed, just as you need.

Note that the Cython project is working on a protocol to efficiently call
external C implemented Python functions by effectively unboxing them. That
explicitly includes JIT compiled code, and a JIT compiler could obviously
make good use of it from the other side as well.
