Make my newspaper available/delivered only for my premium subscribers.

I have paid subscribers in my website. I want to offer them, as a paid service, content curation exactly like paper.li.

That said, what I need is that paper li is available only in my website (embed or whatever) in the premium section and the email delivered only to the premium mailchimp list.

What this means: I need a private newspaper where people cannot subscribe themselfs and cannot share the page for other people (it will be behind a paywall in my own website).

Is that possible with paper.li? Will this be a feature to be implemented? Like a semi-private newspaper or something like that?

thanks
