What is “3 Permanent Dolphin Licenses” for Prime

Hi All

Can anyone help me out with point "3 Permanent Dolphin Licenses" for Prime Package? 
1) Dose it mean that I can use same license at 3 different domains name or 3 different server ip's.

2)How is it for sub domains? Is it possible to use this key for development environment for example if we purchase this key for xyz.com can we use same key for dev.xyz.com or xyz.com/dev

3) Can I stop using key from one location (domain or server) and use it for other one?

4) Also will this key be consumed if I use it for local dev env.

5) What if I shift site from present server to other new one or any other detail I should know.

All these questions are based on fact that we are planning to have demo, live, testing and development locations different.

Thanks in advance

It means you are given three permanent licenses, which will each remove all link-backs on the script. You may use a license on an installation that resides on a subdomain, but you must remember that you may use only one license per installation. If you need to re-use a license on a new domain, you may reset your license through your account page and re-register it within the new script installation on the new domain. You may only have one script and domain tied to a license at a time.
