Okay, so at X>300MB* this could hypothetically come as an update to the ServiceWA app, and then every phone that has that app has a functioning offline map of the whole of WA?

So someone driving in the outback has that back up there, ready to direct them the quickest way to where they want to go?

Could even have a push notification as the app detects signal loss to remind the user of the option to use the map.

Thats seriously cool, but also could save someones life if rolled out like above.

*I say x>300MB because I expect there'd be some bells and whistles to add.
