It first transfers the module to the remote host and then executes it. I am guessing that it copies it to /tmp directory, chmod +x <file> and then executes it.


Not "/tmp" specifically, but "a temp directory", yes. Depends on the user.

Yes, Ruby can't run without a ruby interpreter, and we do execute modules on the client (because they have to change stuff).

I don't expect anyone to be writing them in pure Java.
