Francois, I feel obliged to tell you that I consider your mention on caterfly.co.uk of OpenSpace Agility and of Daniel Mezick insufficient. And I cannot see ANY open source license on the website at all.

In other words: You are probably in breach of the open source license under which Daniel published Prime/OS and OpenSpace Agility. It is not up to me to act on this, but I think you should do more to refer to the original license appropriately, and to make your own open source license more prominent (if it is there at all). Daniel Mezick of course is the person for you to talk to, if you are in doubt about the intent of the license.
