jsb,
WOW!
Your DD's giftedness is probably one in a million even rare among DYSers. I don't think there is any gifted preschool program. They do (mensa for gifted youth, etc..) but they are for moderately gifted kids.
I suggest you apply DYS program and ask family consultant. They probably have more resources. But the chances are you have to home school her (but I don't know what you will teach her after calculus) until she is ready for college.
It sounds like she is mature beyond her chronological years and you may have to let her attend college before long. If I were you, I would ask her to take SAT, discuss with reputable online colleges (scholarship, etc..) and do online classes. (If she is willing of course.)
