Facebook Connect/App Implementation Overview

Question

I am just starting to design a Facebook 'app' that I would like to see work similar to the Netflix Facebook app. I have looked high and low on the Facebook developer site for details how how such an app might be implemented, but most of the documentation seems geared twords websites where a user is already logged into Facebook.

Are there any good references for implementing something similar?

For those unfamilar with the details of the Netflix app, here is how I would like to see the user workflow work.

1. User authenticates with an app running inside Facebook to setup this connection
2. User interacts with my website (they may or may not be logged into FB).
   1. Certain predefined user interactions will post to their FB wall.

I think the big problem I am seeing is that I am not sure how to enable posting to a users wall while they are not logged into Facebook.

I have seen the following reference that suggest that something called an 'infinite session key' is what I am after:

But considering all the hoop jumping the article walks you through I do not remember that being what I had to do to enable Netflix to post to my wall.
