I no longer have a copy of the "AppleTalk Network System Overview" or I
would provide you with a direct quote. I will, however, paraphrase:
An AppleTalk zone is a logical grouping of AppleTalk
networks in an inter-network configuration. An AppleTalk
network maps into a segment or wire. An inter-network is
two or more AppleTalk networks (combinations of EtherTalk,
LocalTalk, and/or TokenTalk) that interact through an
AppleTalk router.
One wire? Zones are irrelevant. Two wires? If they are connected via a
routing device, then Zones _*can*_ be defined (but why?). Since netatalk
does not _*route*_ AppleTalk (unless Wes has performed some magic without
telling us), two interfaces on two different nets does not an AppleTalk
inter-network make.
Even so, the reason to define zones is to simplify the grouping of network
resources for the user (as they appear in the Chooser) -- and to reduce
broadcast traffic -- on a large diverse inter-networked LAN. Other than
for the purpose of experimentation, can there be any reason for subdividing
an apartment LAN into zones?
