It would be highly valuable for this plugin to allow the following:
1) Controlled access to premium content such that a website visitor can view a certain number of ANY premium pages(content). The user decides what he wants to view but after a certain number of accessed pages he is prompted to register for paid membership/subscription.
2) Targeted at premium pages with video content. After viewing the page for a certain period of time, a hovering layer blocks content, prompting for sign up.
This solves the problem of the publisher deciding which pages to "protect." This is a problem because EACH user has different interests. For this business model to work, the visitor must "fall in love" with what they see and experience. This feeling of product satisfaction is what urges a purchase decision. Hence, this feature saves the publisher time; and creates more effective sales execution of the digital content.
