Sounds like you have done some really important networking locally, which is very important.
I have had no luck with creating a local group, but I do keep in touch with local parents through email and phone contact, and when legislation came before out state recently I was able to get folks to email their representatives.
Is the homeschooling Mom willing to homeschool your daughter? Could your daughter also go to the Geometry Class at the HS?
I do believe that there are resources out there to help point you in the way to "go" rather than "gripe" - Karen Roger's Re-forming gifted education is a book that tells you what to ask for.
Have you considered a gradeskip for DD? The program may suddently be "much less of a snooze."
Best Wishes,
