Folks, I am about to release a new paid-for add-on and was wondering - how do others with paid add-ons protect their work? Seeing as it is PHP and the user will have the source, it's almost impossible for me to put a phone-home-and-check-key feature in because it can be commented out. So, unless there is a way to compile php to a binary then what options do people have? I know there are null communities out there, I've browsed them but never actually used them. Curious... C.
