Facebook "like" button on comments

Question

Is it possible to implement the Facebook like and share functionality for "liking" the comments of other users on a website? Does every comment has to have a permalink?

Answer 1

I have asked the question on Facebook developers forum, and they have come back to me with this response. Basically, the functionality that is required is not available.
