> LLVM's bitcode is an intermediate representation, not a bytecode (last time I looked at it, you couldn't even move it from one architecture to the next and be sure it worked) Most of LLVM IR is portable, but naturally there are target-specific parts. If LLVM IR was to be used in the web, these target specific parts would be defined for the "web" target. LLVM IR is used in a similar manner in NaCl and OpenCL where it is used as a portable binary format. > Bytecode is very much a hard part if you're trying to support more than a single language It's not easy but it's mostly a solved problem. JVM was designed with a single language in mind, yet it's used by dozens of languages today. Similarly LLVM and CLR are widely used.
