Explanation of licensing?

Could someone please point me at an explanation of licensing requirements/setup for Rhino Inside?

Does it require licenses? Or does it bill by core-second of usage like Rhino Compute?

To be able to use Rhino Inside you’ll need a Rhino installation with a valid license.

If you have a product that can use Rhino Inside then each user of your product needs to also have a Rhino installation with corresponding license.

This is different from Rhino Compute.

Thanks Nathan. Can it use licenses on a Zoo server?
