Actually, they're not any different, aside from scale.  Some private
internets have hundreds to thousands of participants, and they often use
obscure protocols on obscure systems that were killed off by their
vendors (if the vendors even exist anymore) a decade or more ago, and no
source code or upgrade path is available.

The "enterprise" networking world is just as ugly as, if not uglier
than, the consumer one.
