If the commercialization of spider silk were a horse race (which penny stocks sometimes are a gamble) and we were all betting on the favorite, and the names of the horses were KBLB, Spiber, Amsilk, Okamoto etc., who would you bet on?
The answer to your financing question is the tag line on the KBLB web site. The future is made in the laboratory - maybe, but the money is made on the manufacturing floor.
Until they can show this can be commercialized - then they won't be able to answer the now famous quote - show me the money.
That is why the JD with Warwick is interesting. If Warwick isn't able to come up with a process for large scale production - this won't work and the stock dies. Should know fairly quickly - Warwick will move fast to answer the go / no go on commercialization potential IMO.
Disclosure hold a small position because the potential is huge if it can be successfully scaled-up.
