Thank's Adam. Also, I have a last question before purchasing the license :

 

For our customer who need a high level of security, we use our CMS on a dedicated backoffice server which is complety secured into a private network and approachable from the Internet only with a VPN conection. I want to be sure we can install "CE for PHP" on this private server without problem of license control.
