You do kind of have to wonder how much it costs HP to
keep running this
licensing scheme...
Well, AFAIK the only O/Ses still working on a per-user fee scale are
the DEC derived systems (OpenVMS and Tru64), SCO, and Microsoft.
Everyone else (including HP for HP-UX) went over to unlimited user
licensing in the late '90s.
Being a hobbyist, I've never had occasion to poke around in commercial
VMS licensing. Do they still enforce the machine restrictions (i.e.
machine X is a "workstation" so it can only host up to 2 users, period,
another machine with the exact same VUPS rating is a "departmental
timeshare" that can host up to N users (with the proper licenses) . .
.)
