There has been research into this exact concept. Gene therapy is where they
use a benign virus to deliver a specially crafted payload (instructions) to
alter a person's DNA. Pretty clever way of curing a genetic disorder. On the
flip side, there are some obvious other uses for this sort of technology that
are probably getting funding under the radar--gene therapy is in practice no
different than genetic augmentation. There have been movies about it already.

That's cool. I didn't know that--but now learning that, it doesn't really
