I think we're encountering situations where programmers who have been
trained very well to work in those situations now want to take the same
approaches and make them work over much wider distances.  

I suspect that API-based approaches have natural functional limitations,
which may not be encountered in tightly governed and deliberately
homogenous systems (or very simple systems).  APIs offer a clear set of
rules, but at a distinct cost to those for whom the design of the API is

(There's a bit of a parallel to relational databases, which are great
things unless your data doesn't mesh well with tables.)

Loosely governed messaging may be, in some senses, sub-optimal for
everyone, but the flexibility there offers an opportunity to optimize
exchanges as necessary.

I suspect the same possibilities are inherent in most systems, even
those inside the firewall. The frameworks we've built those systems on
tend to snuff out the lines of thinking which might have brought us
