copy protection

Hi! Has somebody thought of adding some sort of copy protection to a PHP project? I guess it would be difficult to accomplish. Say you have some PHP scripts for mantaining a web site. You don't want the ISP simply copies the scripts for each web site he wishes to use it for but buys a valid license for each copy. A solution would be a license key that guarantees the scripts are being used only on a specific web site / domain name the license has been buyed for. One problem is that PHP is source code, it isn't stored in compiled form, and a copy protection could be easily located and removed I think. Ok, there is Zend encoder but it is very expensive in my opinion. Are there any tools, articles? Did ever have anyone this problem?
