Spider Web Composite Armor - Biomimicry

I love biomimicry, and in particular, natures' ability to manufacture superior composite materials. Spider silk, known to be one of the strongest materials per unit of weight has made news yet again. A start-up called EntoGenetics has recently received a grant to produce spider silk from a silkworm:
"EntoGenetics has developed a method for transferring a spider's silk production gene into the common silkworm, creating for the first time a commercially viable method of spider silk production. This fiber will provide soldiers with life-saving vests that are tougher, lighter and more comfortable to wear than current vests made of Kevlar and other similar fibers. It will also be used in promising medical, aerospace and composite applications."
