In relation to opcodes, I'd also like to note that Faust-written opcodes are running in Csound at near-native speeds 
via a LLVM bytecode on-the-fly compiler.

LuaJIT is, all by itself, a high-peformance virtual machine with a built in foreign function interface. At this time, Csound can embed LuaJIT via the Lua opcodes. This is installed, for example, with the Csound 6 app for Android.

I don't know, did you package them? The code only depends on faustlib (from faust2 git) and LLVM.

That's a pity, it does work well on OSX & Linux.
