I have seed for Sedum oreganum and Sedum acre. I have some large expanses I would like to try it on. We probably won't have a frost until Nov...unless we get a freak weather break. My question is, should I plant now and hope they get enough growth to survive the winter...or just wait until Spring?

I have never tried sedum from seed, other than it self sowing, so not sure on what works best.
Have you ever tried Winter Sowing? I would think you could use this method with success, and transplant the seedling in the spring.
Or you could try some of the seed both now and in the spring if you want to sow in the ground.
I would love to see an update on what methods you use and how it does.
