So I went back to my books last night and have some questions and ideas:
1. Does Mazy allow you to touch her front paws? If so, I can tell you the areas that map to her GI system -- perhaps some Reflexology might help. There are areas on the ear and face that also map, but I don't know if she would tolerate it.
2. Perhaps abdominal massage, again, if she would allow it, would help move things along. One of the schools I had looked into for a small animal massage program had a DVD which I just received. I haven't watched it yet, but hope to do so in the next few days. If Mazy would tolerate it, maybe there's something on the DVD that would tell me where a massage would help her.
3. The focus to this point has been on motility and breaking up the fur (using lecithin). The gallbladder stores bile and releases it during the digestive process to break down fats. So I wonder if perhaps her gallbladder isn't producing enough bile. I also wonder if she's not producing enough mucous to help the fur "slide" along. I know you add the slippery elm to help with that. You can also give her aloe vera juice -- a holistic vet I went to had me give it to Pookie's sister for a time, but I don't remember the dose. You can give them the juice (not the leaves) and it's very soothing to the GI tract.
4. Is there something going on that could be stressing her? That might be contributing to the issue.
Other thoughts: you could add colostrum to her food to help her nutritionally. I don't expect it to stop the hairballs, but since she's bringing them up with food, adding the colostrum would be like adding a "multivitamin" and help boost her immune system. I like this company:

http://www.wholisticpetorganics.com/wholistic-bee-powertm.htmlI mention these because I'm a bit concerned that her nutritional needs are higher than normal, even with an all-raw diet, and adding nutrients might help her body heal itself. But I'm just tossing these out there for your consideration. You have to go with what you think is best.
I want to research more, but some other things I found: glucosamine plays a role in the secretion of mucous in the digestive tract and other body functions. MSM promotes gastrointestinal health, sea mussel aids in the functioning of mucous membranes, reduces inflammation and promotes wound healing, shark cartilage can be used to reduce inflammation in the bowel lining (which probably doesn't help with the hairball issue, but might help in other ways). Glutamine "provides fuel for your gastrointestinal tract, particularly in the cells in the linings of your small intestines. According to biologist George Mateljan, author of "World's Healthiest Foods," glutamine also provides the main structures for these cells to help them resist against disease-causing microorganisms and minimize the absorption of allergenic molecules." [http://www.livestrong.com/article/287131-glutamine-vs-glucosamine/] But like I said, I want to look into these more to see if they can be given to cats. I'm sure glucosamine is safe (it's used with chondroitin for joint health), and probably MSM, but I'm not sure about the others.
Meanwhile, try to get some sleep!
