I disagree a bit. Any other vendor using a mapping service, from Google or other provider, doesn't turn around and tell their customers to setup billing and linkage for the map feature!
If Ruckus wants to provide a mapping component in their product, then they build-in any additional costs for that component.
Given that we're already paying for a 'Cadillac' of network management product, the use of Google Maps in the ZD console should be included!
