I found a bootloader the other day that professed to secure the code. It set a code protect flag in Pic. I have just been googling for it and it has gone. Or rather my memory of the search terms used is gone. How annoying.

I guess it comes down to the Pic. Is it possible to stop people reading the code back out. If the Pic doesn't have the capability, then it isn't going to happen. I will keep looking and will post if I find it.
