I dunno if I agree with the ethics of this:

5 healthy designer kids born, for the purpose of providing donor tissue match for an existing sibling
I dunno... bringing children into the world just to cure another kid... seems a bit too servile to me...
Even if these parents say they will love all the children in this case, how can this be extrapolated to every future occurrence of this?
The technology might be abused, and kids will be born for all kinds of frivolous reasons
Suppose I create a headless clone to supply me with extra body parts?
At what point do you stop? It could sort of undermine the definition or value of a human being
