Hi Format, ahm, yes, I am late, sorry. 
Thanks a lot for jumping in and posting it for me, i was in the crunch with other releases…
It seems their business model is based on providing free addons for Max / Blender and selling sdk
I thought it is the only logical combination: Blender 3D Artists should have it for free, the commercial industry supply and development are in position to license it.
I mean, I can turn it around, but I am not sure if it is then compatible with the user-friendly Blender philosophy?
I have now created an official thread to UV-Packer in the add-on section. UV-Packer Add-on.
Thanks you all, I have learned a lot from you here - the add-on is indeed inspired by all those great people posting their developments in the addon section! see you later
