Morten St George Theory

[Morten St. George]

By the 13th century there was a flourishing industry in secular scribes making manuscripts. The main reason were students at the new universities who needed copies made. 
Once the private industry was setup, the scribes quickly organised themselves and started bidding for lucretive work creating manuscripts for private buyers such as rich patrons, teachers or lawyers.

David, Are you insinuating that the VMS could have been compiled by university scribes? Sure, but I've been reading that the Cathars of the 13th century were highly literate so I imagine they would not have needed the help of professional scribes. As you may or may not know, authorship by Cathars is the only sensible explanation for the survival of only a single instance of Voynichese because a massive effort was made to destroy all of their literature. Authorship by monks, sexually perverted or not, or by a mad scientist as suggested by some, are not sensible alternatives.
