Below is a video of a British couple talking about their homebirth using HypnoBirthing(R). I don't know how common this is. I currently have my first official homebirth couple after nearly 8 years of teaching!
I say 'official' because my best friend did use HypnoBirthing for her home/water birth, but she didn't take class with me because she lived hours away. I attended her birth and did use the techniques with her, and I did give her a book and CD set. However, I wasn't sure how well it would work for her without the 12 hours of instruction.
In the end, she had an hour and a half labor for a 10 lb. 4 oz. boy, over an intact bottom, oh, and a broken tail bone. I guess it worked!
And here is a video of a woman who had a painless birth using HypnoBirthing for her hospital birth:
