Quote - No matter what way you look a it; at this moment in time you can not use Vue or it's modules commercially unless you start with Esprit or higher.

I think you're wrong, see this thread where someone asked roughly the same question -> http://www.cornucopia3d.com/forum/viewtopic.php?t=7900

Essentially it would appear that once you get the right combination of modules, your edition of Vue changes into one that matches that combination, i.e. just like previously Esprit + modules == ProStudio.
