I'm not sure what the requirement for purchasing CALs has to do with whether an OS is multi-user or not. I have administered or been a user of interactive remote NT user session systems going back to beta testing the initial release of WinFrame in the mid 90's. Although worlds better today, I would not have called it pisspoor even then. Today RDS is much more capable than X on a unix system.

As someone else in that space in the mid 90s I would agree that it was pretty remarkable nearly 30 years ago, especially considering the competition.

As far as I know NT 4 was not able to have 2 users logged on at the same time. So it was not a multiuser system.
