Thank you for your extensive answer Sven, and for lifting this into a new thread. As you say it really deserves to have it's own discussion.

As for making code public. In normal cases I would have no problem with giving back code to the project but in the case of this one client the IP of the graph lies with them and it is not negotiable that it should be made public.

I am quite sure though that if I get to create their graph that I would have the basis for something that could be made public just with a different type of graph.

Best regards,

Martin
