Ah Eunice. There was a project to run Unix binaries on VMS. From that
project at least two TCP/IP stacks were born: Wollongong TCP/IP and
Multinet TCP/IP. Wollongong basically bought the rights to Eunice and
made it into basically a TCP/IP product as well. The guys that did Eunice
originally went back and created Multinet which is a radically cleaned
up version with many thing rewritten for speed. Eunice started out life
from 4.1BSD and was later based on 4.2BSD and 4.3BSD. Ultrix was
also based on 4.2BSD.
UCX was a different beast... As was the package from CMU...
