How many CALs does Print Audit use? (SQL)

Server plus Device CALs. We would consume one device cal per Database Communicator, and one for every desktop where they install tools other than the Client, Copy Audit Touch or Embedded. (These all use the Database Communicator).  Additionally each instance of Print Audit Secure (Server) would consume an additional CAL.

Copy Audit Communicator (for Copy Audit Numeric,) if installed on another computer than the Database Communicator, would also require a CAL.
