Zone names are groupings of network numbers.  You do not have to have a unique
zone name for each network number.  If you have a localtalk zone named (for
example) Ardvark, you can also configure your ethernet routers to display
Ardvark on the ethernet segment.  The network numbers must be unique but the
names don't have to be.

On ethernet, any user can select which Zone they wish to reside in.  The
advantage of this is that an ethernet user who shares services in the Ardvark
zone with other Ardvark users selects Ardvark as their zone.  Whenever they
pull down the Chooser, their selected zone will default to Ardvark.  If they
immediately click on a service icon (left window in the chooser) they will get
a list of all the devices that live in all the networks out there that have the
Ardvark zone name.  Makes it easy for the users in a group to stay together and
share resources.

Troubleshooting will not be affected by your choice of zone names (2 or 25).

There is no zone limit in Chooser that I know of.
