well, you are right on one thing. System requirements are NOT enterprise
policies only. Please comment on where in RM-ODP do they fit in?

That, depends. If the requirement that TCP/IP be used is major enough, the
enterprise might make it a business policy : "All future systems will
use/support  TCP/IP". An existing example may be found at home. Depending
on how important CORBA compatilibity is, Baptist will probably make(or
already has made) it a business policy "Thou shalt support (provide) CORBA
services". 

Kent, listening?
