I'm pretty sure the guy in charge of our switch-and-cable infrastructure hasn't connected any switch to more than one zone - because I've specifically asked him before, he gave me that assurance, and he's a smart guy. But I'll ask again. Meanwhile, if anyone else here has a suggestion, the working assumption is that we don't have an example of the "Fool's Firewall" (as it is very clearly explained on Tom's page) so other suggestions will also be appreciated.
