I am not from Laminar Research; just a flight simmer from down under.
As your intention is to be a multiple user (?) I would suggest you contact Laminar Research direct to solve your commendable project. I am of the opinion that you may need a professional user licence which may cost less than purchasing 13 copies at the single user cost. Start with the following link at email@example.com or call 913-269-0976 if you live in the USA.
Good luck with the project.
