There are several vendors who use JRuby to pre-compile code for
release as packaged software. The pre-compiled code is just JVM
bytecode, so it's possible to decompile it to something...but it would
be hard to duplicate it without a lot of effort. Since you can also
bundle it up inside a .jar file and provide a simple executable, most
users would never bother cracking it open. Using JRuby has the added
benefit that your bundle doesn't need to be rebuilt for any platform;
if there's a JVM installed (and there probably is), it will just work.

My opinion: despite what others on this thread have said, sometimes
there's a real need to at least make it difficult to reverse-engineer
code when you ship a packaged application. Using JRuby is probably the
easiest way right now.
