Note that they haven't managed it yet on monkeys (surprised me).
Prediction: when it's been working perfectly on all primates for quite a while, these laws may start to change... perhaps at first for special cases, such as infertile couples (or a clone of an infant who died of non-congential causes - I don't know what to make of that, it's simultanesouly creepy and tugs at my heart-strings). IVF programs have similar restrictions.
