I think that geographical and routing zones must be two separated entity
because they are completely different concepts and it will be a big mess
to join them together

I think that we need a common minimal but extensible type "device" or
something similar, so each devices can have also particular properties,
all other kind of stuff like servers, router switch ecc ecc should
inherit from this type or a subtype and that should be done easily by
the user who add the device,
so that devices will have properties and each property should have
get/set(if writable) method which tell to the mapserver how to handle
an example could be the SSID the map server can get or set that value on
the device but it need to know how to do that for example:
ssh_shot $HOST '
config_get meshSSID wireless "meshSSID"
ssh_shot $HOST "uci set eigennet.wireless.meshSSID=$1"

maybe you some devices like hotspot doesn't have that so i think this
should be out of the core too
my 2 cent
