I wouldnt do it, because of exactly what all the others are sying. even if you tried to have this child bring his/her own food, you also run in to the issue of the others not only wanting what that child has but also, its possible other children could develope the "if he doesnt have to eat it, why do I?" response. that can quickly turn into a chain of trouble. no offense but in this day and age if you want to be different in a social society, get ready for turmoil. Good for them on sticking to vegan living whether its religion or something else, but good luck finding someone willing to go the extra mile. Had a mom come to me the other day for care and said, by the way, my kids dont eat ANY sugar or nitrates. I SAID, no thankyou.
