Cool, but why not just use, you know, Java bytecode? Existing toolchains, compilers, runtimes, virtual machines could all be reused I'm sure. Actually there are a hundred different great virtual machines that could be used... Why, yet, another?

All the compiler backend/code generation is using LLVM, and the VMs are all pre-existing (JavaScript with some extensions), so there is a huge amount of existing code being used here.
