Espruino loading source code from SD card?

OK, I agree the Espruino doesn't have JavaScript code protection without the user going to great lengths in writing specific code for encryption.

On the second part, of the user writing a "simple bootloader" to the Espruino for
auto-booting via transflash drive, is there anyone on this forum board ever attempted to write a simple bootloader for the Espruino? Any code examples are welcomed.

function onInit() {
  exec(require('fs').readFile("boot.js"));­
}

BTW ... I hope I did not misunderstood that "boot.js" is actually the sd file user application code
and not the bootloader code? (The bootloader code is the code above?)
