+the thing that updates sets has to know they exist, so the interface watcher
+service must live in the firewall module
+
+the firewall service defn should return the firewall service after
+adding the interface watcher as a dependency of it. Or: the watcher
+should make the sets and then the firewall service could depend on _it_.
+That would mean that the firewall service would fail if it used sets
+that the watcher didn't make, is that good or bad or indifferent?
+
+the interface services have to know about the watcher as well in order
+to write into its outputs, so it can't be hidden inside the module
+
+maybe the watcher service should _be_ the firewall service.

+we could add a "notify" param to an interface which would be an output
+reference to (the firewall service / zones / lan ) that the interface would

+another thought: the firewall service could have params to say
+which interface services are in which zones

+we'd have to ensure that the interface services did not end up as
+dependencies of the firewall
+
+then the firewall could watch each interface service for the ifname
