re: C++, ACE, SCE, TMN, CORBA... had enough abbreviations?
  Thanks much for that clarification, Jay. Of course, simulation and modeling. It didn't strike me as such, at first. I was looking beyond into your meta phases, thinking that they were referring to the real thing in the way of actual network drivers, routines, etc. 
  Take a look at the Adaptive Communications Environment (ACE) page below, for an example of where I thought the reference to C++ was headed:
  cs.wustl.edu
  When I came across ACE the other day I realized how it was almost an inside-out view of some other architectures, but of the centrist persuasion instead of distributed in nature, that are now being displaced, such as the Bellcor/ITU model surrounding Telecommunications Management Network (TMN) principles, and the associated Service Creation Environment (SCE) tools, both of which are (or were?) also heavily dependent on C++, and later, CORBA, as well.
  [[The SCE, incidentally, is an area, when it is refined and adapted to IP, where on-the-fly features and services are likely to be under direct control of users, in relation to one of your questions about the future of VoIP, recently. I believe that you asked how service providers will be able to differentiate themselves, when bandwidth costs were reduced to zero, or something like that. It was back in the replies to the bandwidth futures discussion, earlier on.  I would like to expand on that point in a later post.]]
  If you are familiar with ACE, I would very much appreciate your commenting on its relevance, how it is being deployed, and in what areas you see it growing.
  I'll need to take some time to review all of the references you provided. Thanks for taking the time and doing the legwork.
