Muslim-Christian families

Firstly, apologies to those who might have read this one on "Your choice" already. Anyway, since I didn't get any reply there, I decided to cross-post this question on a few other branches, too.

What do you think about bringing up children with both Islam and Christianity in the family? I know that theoretically it's impossible since only a Muslim man can marry a Jewish or Christian woman (and not the other way round) because he is expected to pass this faith on to his children, and I understand that his willing to do so (and the woman accepting this) is a precondition to his marrying a woman of another religion.

But does any of you have any own experience with this? Anyone brought up with one of the parents being Muslim, the other Christian? What do you think? Not only about the child getting confused or not (I've been pondering about this for quite some time myself.), but also more specifically about the limits given by Islam for passing on both religions to the child and the possibilities of still doing so or not.

And does any of you know if there's any sura/ayat in the Qur'an that explicitly deals with religious education of children (I know about the implicit logics that you should do what is best for your child, and by being a Muslim you are convinced that this is the way, but am wondering if there's anything else in the Qur'an or any Hadith?)

Thanks a lot.
