Where is the confusion coming from here? Localtalk was the physical layer that Appletalk was originally designed to use via LLAP. Appletalk was later applied to other hardware (ethernet, token ring). Acorn also had peer-to-peer networking prior to Appletalk. Hermann Hauser's Appletalk quote comes from this old article <URL: [link] >
Right, that's it. No more about econet or Appletalk, let's move on.
Another interesting paper that mentions Acorn: <URL: [link] >
Bringing the discussion back on topic regarding Acorn's legacy, it claims here that Acorn gave rise "to more than thirty start-ups". Also, it claims that Commodore wanted to license Econet, but Acorn said no. Aargh, I mentioned Econet again! *la la fingers in my ears*
