My understanding is that in this approach, rather than producing a long sequence of DNA, they're making tiny sequences of address and data snippets, then assembling them with enzymes randomly. Containing addresses allows the data to be assembled back into the correct order.
With typically three base pairs per amino acid, encoding complex proteins in 30 base pairs isn't possible. That said there are other methods to assemble longer sequences.
Nothing is technically stopping someone from writing a deadly virus, except that you'd have to engineer its DNA (not a trivial task). Why do that when nature has created plenty of deadly viruses to choose from? Furthermore, for military purposes, you would want something controllable, so you can deploy it without also killing yourself. Bacterial agents tend to be more suited to this.

I wonder if oligo synthesis companies have black lists of specific sequences if a random person orders them. Also, many viruses are RNA based. More tricky than DNA. But in that case I would just order DNA, build a complementary DNA virus and then use RNA polymerase to make the RNA. " for military purposes, you would want something controllable" I am not sure the guys that I am thinking of that would be interested in such a thing would worry too much about that. I guess if you are willing to fly a plane into a tower then you would not be too concerned of dying in the process of developing a virus. Better than a virus may be the Mutagenic Chain Reaction. Maybe my genes are better than yours and I want to spread mine? ;-) http://science.sciencemag.org/content/348/6233/442 http://science.sciencemag.org/content/348/6233/442 "The threshold necessary for small groups to conduct global warfare has finally been breached, and we are only starting to feel its effects. Over time, in as little as perhaps twenty years and as the leverage of technology increases, this threshold will finally reach its culmination -- with the ability of one man to declare war on the world and win."

Terrorists getting hold of viruses has always been possible. If someone were so inclined, I'm sure they could get hold of an Ebola strain and pass it around somewhat, using no special technology.
