I don't want to mix license system for a given library. It would be too complicate for the end users. I guess that for those who are not aware about free license, it must be already not that simple.
But as CC-BY seems to be more popular than LAL nowadays, I would like to write to all contributors to get their agreement to distribute their models under CC-BY too. But if I don't get the answer or agreement of only one contributor, it will become a mess. Not a very motivating task, but in case of success all the models available in the 3D models page would be available under CC-BY!
By the way, the 65 GPL models available in Sweet Home 3D were designed by me, so if ever all contributed models can be available under CC-BY, I won't mind to offer these GPL models under CC-BY license too.
PS: Before all that, I have to study in details the difference between LAL and CC-BY.
