I sure could help a push into the right direction.
Is there a plugin that allows me to restrict a specific subscribed user to comment on a specific page only?
I want to be able to create something like a personal 1-on-1 chat page that only me and a specific user can comment on, while everyone else can only read but not comment on that page.
Also (probably my real problem), it has to be scalable... meaning, I need to have this functionality for multiple users, each having "enhanced" access to their own, personal page where only they (and me, the admin) can comment.
I would work with password-restricted pages, but I want the world to be able to read all those pages... I just need to be able to restrict comment-ability on a per-user basis.
