The money was just to pay for the tape primarily. There were no restrictions on
redistributing the data (over and above the WE license). I remember hustling tapes
through customs on the way to the UT Unix conference back in what 1979. Since they
didn't really have the production to write everybody a tape that wanted one they
picked a few people who were centrally located that could get copies and redistribute for
them. Since we (Johns Hopkins) had brought several of us with tapes, we got one to
bring back.
