Summary: Nope, use source code. Bytecode isn't shorter, anyway.

Oh, and LJ2 doesn't even *have* a bytecode loader/dumper at the
moment. It simply wasn't a priority. Open source projects using
LJ2 have nothing to worry about, since they don't need to hide
their Lua sources.

The idea was to make a commercial add-on for bytecode handling.
But I'm not sure it would pay off (required work + support
overhead vs. money in return). There are cheaper ways to hide your
Lua sources: simply compress and encrypt them. And bytecode is
easy to reverse-engineer, too.
