Hi Ren - i don't have any gifted music genes (well, i do have some jeans with music notes on them!), but i just wanted to say that I'm happy for your DD. I think that this will give you more choices in schooling for her. I don't think you need to worry so far into the future yet - just see how lessons progress.
S-T - I remember seeing that video on TV. I had forgotten about it (use it or lose, i suppose!). Very interesting, especially when talking about the different parts of the brain musicians use. Makes me want to go sign up for piano lessons myself!
