I'm working on something that could be applicable to this! There seem to be many areas that would benefit from a pluggable JIT engine, so I started building one: https://github.com/nitrousjit/nitrous/ https://github.com/nitrousjit/nitrous/ It's designed to analyze and optimize existing codebases. So far it's produced some pretty decent speedups on the Python interpreter, though with a big drawback of very high compilation times due to using LLVM. Let me know what you think or if you have performance-sensitive programs that you think would benefit from a low-investment JIT.
