j-art Can't comment on the German Version. I will leave that for Wabe, bus as for your other questions. Yes Vue has come a Loooong! Way since Vue 4 Pro and as you have seen the images can be photorealistic. Floating version - For companies, studios who want the option of having their Vue liscence on multiple machines or on a network. Node Locked - For individuals or anyone who wil be primarily using Vue 6 on 1 computer or maybe a computer and a laptop, but tboth computers must be owned by the same person. Sorry this is in layman's terms. I'm sure Wabe or someone else can explain it better. I have used Vue Esprit, Vue 5 Infinite and noe Vue6 Infinite on a mac with no problems to speak of. In fact I wouldn't have it any other way. Hope this is of some help and hope to see you around the forum.
