I am making a cake for DH's retirement ceremony (bit off way more than I can chew, but will have to make it work). Anyway, co-worker told DH about a local cake decorating shop that I had never heard of so checked it out online and could look up some of the products they sell. They carry americolor which I knew from here that was nut free. They also carry Satin Ice Rolled Fondant.
This is from their website:
Zero g trans fats, Zero mg Cholesterol
Gluten Free, Dairy Free, Nut Free
Fondant contains no animal derived ingredients. Gum paste contains egg whites.
Certified Kosher Pareve
I have not called the company to check if "nuts" include peanut (we are not PA).
I also don't know how easy it is to find.
