I have given this issue a fairly extensive treatment in an IT architecture document I prepared some years ago for the DVA. That paper was reviewed by VistA IT architects during its development. Some on this list may have copies on hand. The paper is a serious read, and not to be considered a 'one-pass' discussion. The document is imperfect, and could benefit greatly from a second, major edition. Even so, it does answer your question and expands substantially on what I have been saying here lately. If you really want to invest the time and energy, perhaps that document can be located for you.
