When the GMO Is a Human, What Then for Anti-GMOism?

No, I don't think we have genetically engineered a human yet, though one could perhaps argue the point. But the Times today reports on this experiment:

By delivering synthetic genes into the muscles of the monkeys, the scientists are essentially re-engineering the animals to resist disease. Researchers are testing this novel approach not just against H.I.V., but also Ebola, malaria, influenza and hepatitis.

Granted, this approach does not alter the genotype, the genes of the recipient, but if it works wouldn't that be the next step?  And if you take that step, do you have much basis for resisting GMO's in crops?
