Shaijee We already offer it through our multi-server license packages...you can add unlimited servers to the same license.
The reason we are not interested in per per-website license is because most of our clients have shared/reseller servers. So per website plan will increase the total license cost and we are not interested in it. Our pricing remains the same since we launched cPGuard and we do not wish to increase it as we add features to our software. To allow mixed license type ( per server and per website ) it requires considerable changes in our billing system. We can do it but we thought to spend that time adding useful features to our software. So we are planning to overcome the same with discounts and introduce smaller plans.
