As I recall E-on bought Poser before Smith Micro. So since E-on owns Vue and they owned Poser for a release it makes sense they wanted Poser so they could get figures into Vue. So since they had the code it was probably easy to put a module into Vue for the Poser figures. Since we all know that the basis's of Poser haven't changed that would explain why Vue still works with current versions of Poser.

Just to be clear Vue only needs to import a CR2 file and like Poser anything it does not understand just ignore it.

The rest of the Fusion plugin's belong to programs that have never been owned by the Poser owners, so don't get the in depth treatment as having the source code provides.
