Hardware-dongle DRM was the default licensing model in the 90s for any kind of enterprise-type software. Pretty much all audio and video production and editing software for many years, and even today. C compilers, for many years, as well. PhysX for awhile. Native Instruments stuff. Saleae logic analyzer software. Another message in this thread reminded me, too, of the Google Play frameworks on Android, which are also a very good analogy - Google ship these libraries licensed for use only on approved phones.
