That's not correct, either.  You can obtain export licenses for the DES
part of UNIX, but on an individual case basis rather than a blanket
license.  AT&T deemed this not worth the trouble.

In general, "technology transfer" IS a concern, which is why, for example,
Thompson & Condon's BELLE was not allowed to be shipped to Moscow for the
international chess tournament.  I don't know whether or not UNIX is still
on the restricted list for shipping to communist-bloc countries.
