That is so cool.
I first read about it years ago - spider silk is literally one of nature's most remarkable products: incredibly strong, incredibly light, super-versatile (used as a structural material, a weapon, a mode of conveyance, and so on). I would buy spidersilk products in a heartbeat.
If nothing else, I'd love to have gossamer-thin yet strong and insulating baselayers.
(I'd say something about "Drow" but I don't want to peg myself as a nerd
