I strongly endorse that recommendation:    (02)

In fact, I believe that encapsulation is the most general and
adaptable approach, which can accommodate almost anything and
everything in a systematic way -- not just legacy systems.    (04)

That is the approach I recommended in the following two papers:    (05)

    Architectures for Intelligent Systems    (06)

    Graphics and Languages for the FMF    (07)

Those two papers were published in 2002 and 2004, and we have
done considerably more work in implementing and using the
Flexible Modular Framework (FMF).    (08)

The minimum overhead for a single module is 8K bytes (note K,
not M or G) plus whatever software is used in the module, which
can be anything from a trivial little sensor to a dedicated
hardware device or an enormous legacy system.  We have used
the FMF to implement societies of interacting agents, which can
be located anywhere across the Internet.  And we've been able
to have over 10,000 agents running simultaneously on a laptop.    (09)
