Drupal (blog) posts and comments on FB

We need to implement following case.

Case:

• When a new (blog) post is created on Drupal it shall be posted on the wall of the Facebook page as well.
• the post can be commented on the website and on the Facebook page, no matter where it is commented, the comment shows up in both places

I had a look at available FB solutions and Drupal modules, what I have found out so far:

• The comment plugin of Facebook is nice, but it seems that it is lacking the possibility to attach the comments to a certain post.
• With the notes FB application and Views it is possible to import the post through RSS, but the FB Comments Plugin or Drupal Comments will not allow to have the comments placed to the according post on the FB wall.

The only solution I see so far is to develop a FB application that the FB page has to install and a Drupal module that will sync the comments with through the FB application.

Before we go down that path I would like to ask if anybody has another solutions for this.

I would appreciate any comments :)
