Especially since the alternative appears to be Java.  Just like
Java, Python compiles to byte code that runs on a VM.

If for some reason he's happy shipping Java VM byte-code and
not Python VM byte-code, then he can use Jython to generate
byte-code for the Java VM instead of for the Python VM.
Personally I think it's rather deluded to think that one is any
more secure than the other.
