FB post comment two way


I am searching everywhere and I can not find.

Is there any plugin that will connect wordpress blog and facebook that will work as one.
So when someone comment on facebook you will see comment on blog, so, wordpress blog and FB are as one thing.

There are plugins which you can set up facebook comment, so you can comment on blog as FB user… and
also there is a plugin which publish post blog to FB…

But I dont see anywhere blog post + comment as one thing on FB.

If I missed somethink, please let me know.

Thanks, regards
