At 32 weeks they have lots of time to turn all on their own. I don't know much about twins either, but I bet the gentlest methods of turning would still work, if they don't turn in a few weeks. Moxibustion, acupuncture, playing music down low on the belly, visualization, all those should be fine. Maybe chiropractic adjustments?
If they don't turn and she doesn't want a c/s, she will almost certainly have to stay out of the hospital, I'd think. Midwives will be hard to find, but it's not impossible. She could try the Farm! If I had breech twins, that's where I'd go, I think. (I had just one breech, and it was a great birthplace.)
