The issue lies not there. Calling would not be necessary when proper install was carried out, and fixing a modified install on user's request by a call to Bondware servers for 99% of users will be preferred over the hassle of sending emails with system info and license code files. Knowing the sensitivity of the topic that 'manual' method would need to be there but relative to total may not see much use.

More fundamental: Python by design is notoriously open and code is difficult to protect to begin with. On top of that, unless Rendo takes care of and responsibility for the protection, everybody is 'in the development house' so the procedures and calls to use will be in the manual. This only then relates to protection of intellectual property. Piracy was also mentioned and that is yet another story.

It is a noble objective though. I wish Tim and his team a lot of success with undertaking this.
