CAD and CASE do need concurrency!  It is critical that many programmers
(or chip designers) be able to work on (different parts of) the same
project at the same time!  Security is also important to many people 
doing CAD or CASE for the military.

Background: I work for Atherton Technology which produces a CASE tool
(actually an IPSE) built on OODB technology.
