View thread replies permission

Hello all,
I am in need of help creating a permission to view replies to a thread.
I want people without the permission to view thread replies in a specific node to be only able to view the OP.
I have no idea where to start.
Can you guys help me out?

P.S. I also think this would be a good idea for something like this to be added into xenforo by default

This is in development discussions, Amaury, so its fairly obvious that he is needing a resource.

However, TheDeNuke, do you have any base for this or are you starting fresh?
