At first I thought that this might be related to Spiber Inc. in some way, but looking into it, i don't think so anymore. Riken is a separate entity altogether. It looks like there will be more or is already players in the spider silk field than first thought.
Looking into it a little deeper, it looks like the may have found a solution or work around to the issue that First Mike brought up in His stickied post #91957.
