That is one means of controlling who gets to see what.  That is using an OS
the protection built in: NT, UNIX, NETWARE(NOT Win9x or DOS)

You need procedures and sign-offs.  This is a problem no matter what
"system"
you use.  Look into using a simple check in / check out system like
CS( which is
freely available from the under GNU open license ).
> 3) Fab data will reside separately from drawing data for redundancy.
Good back up scheme, but again a problem for configuration management.  See
RCS above.

Yepp.  Fab House specific.
> 5) Are there software packages that automate all/some of this process?
Which process are you speaking about?  Placement, design, documentation,
etc.?
