Pymothoa: JIT'ing Python Over LLVM
Phoronix: Pymothoa: JIT'ing Python Over LLVM
Here's another interesting open-source project that's leveraging LLVM to do some interesting things with the Python programming language...
Cool but it still sounds like it is a bit invasive.
This one might be worth following. I do hope it has greater longevity than some Python compiler strategies.
This will be great, what with LLVM being known for its performance and all.
Unladen swallow appears to have been abandoned for a while now.
The one that is actually relevant would be PyPy, which has been under active and continuous development.

On _average_ it's 5.42x faster then CPython.
There's also Cython, which seems somewhat similar: It can be used on straight Python, but benefits from adding type identifiers. It's not JIT, though - modules have to be compiled to be used (though it can be done as needed on import).
Seems fairly active, too - their github page has daily commits.
