I am seriously considering this as well, but I would love to hear about some experiences as well. They had a booth at my Unitarian Universalist conference and a friend told me about talking with them.
I hope someone pipes in!!
Wow, I'm just checking it out--it looks fascinating & very in line with our liberal Quaker values. I would also love to hear from someone who's used it. The curriculum samples they offer are helpful for review.
onyxravnos - Thanks! Please do let us know what you find out. From what I could tell on their website the high school part has been in existence for awhile while it seems like the K-8 stuff is new. I'm really tempted to get it, but I'll be watching to see what you find out.
