I hope that someone who really understands all of this IDL Bridge stuff and
who doesn't use objects for every programming task will provide a simple
description for civilians of just what this capability can do for the
everyday user, and what it can't do. I'm having trouble figuring out whether
this is a cool feature that I'd be crazy not to employ, an easy way to try
to do parallel processing, or something that would require me to reprogram
everything I do to obtain the leverage from multiple processors. So, all of
you Ernest Hemingways out there, how about some simple, declarative
sentences with an example or two of how this feature works and why it is a
Good Thing. Many of us will be grateful!
