Crossroads can't read or write mqo files. I also want to add some functionality such as scaling. I did download crossrods dough to se if it has those options (have not tried it yet). When it comes to contacting the inventer I will wait and se if Hatsumi can get in contact with him first. (Hatsumi: Please let me know if you succed.) About the legal issue of this I know nothing. I'm only a 3D hobbyist not a layer. ;)
