To the original poster,
 CNMs are legal in NC, and there are 9 of us (and one OB) through out the state with homebirth practices, We are scattered from the far eastern parts to the western parts. The newehomebirth CNM practice is mine and I'm near Hickory. I cover about a 2 hour radius & that includes Charlotte, Winston salem, Asheville, Boone and more.
I have 2 backups (working on another one in Asheville) and one was my informal backup for all the years (since 1985) that I was a direct entry (also with my RN the whole time). Acquring backups is getting easier. I had been on the  CNM path for a total of 30 years, so do not give up. I am thankful for all my years as direct entry, and I remain very hands off, and still wildcraft about half of the herbs that I use. I am also looking for an assistant/apprentice/midwifery student. The nursing board is realizing that the state could be friendly to homebirth CNMs and there potential backups, and the CNMs and ACNM are all working to change wording in legislation to "collaborative care", instead of signature of formal backup.  In some states it seeems that there CPM licensure/status is always being threatened. CNMs do not have that concern. Also, a benefit is I could move anywhere and I would have very little problem being recognized as legal and trained in a program that is recognized universally. I can also teach, which I did for 2 years (clinicals in nursign school) so I bring a natural and more consumer oriented approach. In fact, where I taught for 2 yrs. until recently, the direcotr of that program specifically searched for homebirth midwives. Since there are more of us now, students are having less problems finding preceptors who have out of hospital practices. Yes, my school is already asking me to take on students. In many nurse-midwifery programs there is at least one instructor who has or had a homebirth practice, and mine had 4 instructors with
homebirth practices. At the program that I went through SUNY @ StonyBrook, You will be required to perform various assignments on homebirthing. The program there encourages students to serach for out of hospital mentors. I expect to be swamped with those requests very soon.
It was in nursing school where I had to jump through a couple hoops that were not related to natural birthing, (my nursing training was back in the mid 80's) but not in the nurse-midwifery program.
I hope my story has given you plenty to consider.
Contact me if you want to discuss more.
