Trent already replied about PyParallels (and yes, we are aware of his work).<p>We are also aware of Pyston. There might be a chance that they could end up using our JIT hooks, but they also started a full year before us so they are not currently structured to plug into CPython like we&#x27;re trying to through the API we&#x27;re designing (although hopefully they will be able to, but who knows).
